Who isn’t searching for the best laptops for running python? Laptops come in all forms. There are some better suited for quick web browsing and others for a mish-mash of writing documents, listening to music, and gaming. Then, there are laptops which are ideal for programming. Finding the best for python programming can be very important and not as difficult to do as you might believe.

Python is a vastly popular programming language and is widely used throughout the world. It’s easy to see why python is among the most used programs of today. It can understand the English language, which allows it to carry out simple commands with minimal fuss and effort. Python comes with a fully-integrated interpreter and that makes it more versatile. Also, it’s able to execute programs effectively. Python is used across a variety of platforms and systems worldwide, as well as with software applications.

Even if you’re a beginner, python is incredibly easy to grasp. Investing in a good laptop is crucial, especially if you specialize in computer programming or web development. Finding the very best laptop takes time because there are many options to consider. So, which are the best laptops for programming and gaming and what should you consider before buying?

Your Purpose for Using Python Programming

For web development, New Mac Book, Asus Zen Book, Mac Book Pro, and Lenovo Think Pad Edge E580 are options to consider. Laptops for programming vary considerably; however, finding the best for python programming isn’t a difficult task. You can find one that’s ideally suited to your budget and requirements.

Finding the best laptops for coding and programming can be tricky because everyone wants and needs something different. What you require in the best laptop for programming is very different from what another needs and that will impact the type of laptop you buy. So, ask yourself why you are using python. Are you interested in web development? If so, pythonprogramming will be necessary. If you can answer the question, you take one giant step towards understanding the type of laptop you need.

How Much Power Does the Computer Offer?

Power is a necessity for a programming laptop. When it comes to choosing laptops for programmers you have to consider how much power the laptops has to offer. Is it strong enough to cope with your graphics card? Is it able to handle programming and gaming? Remember, gaming laptops can also be used for programming because they carry a lot of power and have more memory capabilities. You want to invest in a powerful machine; that has to be among the top priorities to investigate when buying a laptop.

Operating Systems

Python is, in fact, available on a variety of operating systems, including Windows, Linux, and Mac OS. However, if you prefer one operating system to another, like Windows for example, then you know which type of laptops to look for. You can narrow which laptops you look for simply by knowing the type of operating system you want to work with. Despite what you might believe, an operating system can impact your decision. Some operating systems are limited to the laptops they’re available with so that will help buyers too.

CPU

Newcomers to python won’t think about the CPU and that’s a major mistake. You always have to consider the type of processor (CPU) the computer has. While the majority of laptops available today can be used for programming, it’ll all depend on the type of CPU available. Even the best budget laptop can be used for programming, as long as it has a good processor. Ideally, you want to invest in a laptop with a strong CPU, especially if you’re into advanced programming. You have to think very carefully about your programming CPU before you buy any new machine.

RAM Capacity

RAM is the memory of the computer. When you buy a laptop computer, no matter your budget, you have to consider the size of the memory available. If you’re going to use the laptop for computer programming, then you want more memory, at least 8GB of it. However, you probably require considerably more. In the end, the more memory you have, the more tasks you can undertake so that’s something to think about when buying the best laptop. It’ll talk about memory, but take particular notice of the RAM size too.

The Graphics Card

A dedicated graphics card can be used with python and it’s an essential part of the laptop. While you may not think a graphics card is a necessity, really can be, depending on what you plan to do on the laptop. They can be used for python programming, as well as, gaming, so you need to ensure that’s available. A graphics card can also be used with gaming laptops.

Storage Type and Capacity

HDD’s are often standard features on a laptop, but for programming, a SSD might be more suited. SSD’s are favored over HDD for programming because they’re faster and make things run faster as well. Also, they improve the overall programming experience and that’s a huge advantage.

Memory is a necessity. As said previously, you want a lot of memory within the hard drive of the computer, with the ability to extend if necessary. Programming uses up a lot of space so it’s crucial to have lots of GB’s available. Whether you want the best budget laptop or invest in an expensive machine, you have to consider computers with a high storage capacity.

The Portability of the Laptop

Few people think about how portable the laptop is, but it’s essential. There are lots of laptops available and some are better suited for a home environment. If you’re going to be running python with the laptop, you want to ensure it’s portable because you’ll be carrying it around. You’ll be going from the office to your home and back again; so it’s essential for the laptop to be light and easy to carry around.

The Display Features

HD displays tend to be more useful for programmers. They offer good graphics and are highly recommended. You want to be able to adjust the brightness of the screen as and when required and that’s why you have to invest in a quality laptop. You’re going to be spending hours staring at the computer screen so it’s essential to have a quality machine.

The Size of the Machine

Typically, it’s recommended for programmers to opt for a 12 or 13-inch screen size, but they can be any size you want them to be. Laptops for programmers can be as big as you want, just as long as they’re comfortable to use and view.

Battery Life and Keyboard

Laptop for programmers should have decent battery life available. It might not be overly important if you plan to use it as home since you can plug up and charge when you need to, but, outdoors is different. If you’re using it while traveling or going to and from work, you need to seriously consider the battery life.

You don’t often think about the keyboard with a python programming laptop, but it’s essential. You’re going to require a good and sturdy keyboard since you’re typing all day. If the keyboard is too stiff, it’ll cost time when typing and use up more energy too. Laptops for programming require good keyboards.

Acer Aspire E15 E5-576G-5762

Acer is a big name within the computing industry and this laptop offers great value for money. It’s ideal for python programming and comes with a reasonable budget too. The CPU is Intel Core i5 and offers speeds of 1.6 GHz. Acer Aspire E15 is able to handle programming software easily and comes with 8GB of RAM and 256GB of SSD memory. It also has a NVIDIA GEFORCE MX150 GPU. Since it has a NVIDIA GEFORCE GPU, it’s a strong contender for being one of the best laptops. Also, it has a backlit keyboard and a 15.6-inch HD display.

This page tells you how to setup a Python programming environment for your Mac OS X computer and provides a step-by-step guide for creating and running a simple 'Hello, world' Python program. All of the software is freely available on the Web. These instructions are for MacOS X 10.13 (High Sierra), but the instructions for other recent versions of Mac OS X are similar.


Overview

The Python programming environment required by this booksite consists of:

  • Python, that is, the Python compiler/interpreter.
  • The Python standard libraries.
  • IDLE, the Python Integrated DeveLopment Environment.
  • The Tkinter, NumPy, and Pygame libraries, which are used by the booksite programs that do graphics or audio processing.
  • The booksite library, that is, a set of modules that we developed specifically to support this booksite.
  • The Terminal application that is bundled with Mac OS X.

Downloading and Installing Python, IDLE, Tkinter, NumPy, and Pygame

Note: The Mac Finder application uses the term folder to mean a container of documents and, perhaps, other folders. This document instead uses the equivalent Unix term directory.

Python 2 is bundled with Mac OS X. However, Python 3 is not. We recommend that you download and install Python 3, and use Python 3 exclusively when running programs associated with this booksite.

Perform these steps to download and install Python, IDLE, Tkinter, NumPy, and PyGame:

  • Browse to the Python for Mac download page.

  • In the resulting page click on the Download Python 3.6.5 button. Your browser will download the file python-3.6.5-macosx10.6.pkg to your Downloads directory.

  • Using Mac Finder Manager, navigate to your Downloads directory, and double-click on the python-3.6.5-macosx10.6.pkg file to install Python, Tkinter, and IDLE. Use the default options. (It's OK to delete the python-3.6.5-macosx10.6.pkg file after the installation is complete.)

  • Open a Terminal window. To do that, click on the Spotlight Search icon on the right end of the menu bar. (It has the appearance of a magnifying glass.) In the resulting dialog box, type Terminal.app followed by the Enter key.

  • In the Terminal window issue these commands to install NumPy and PyGame:

To 'issue a command' you should type the command followed by the Enter key.

  • In the Terminal window issue the python3 command. You should see something like this:

  • If you see that output, then your installation of Python, IDLE, and Tkinter was successful.

  • At the Python >>> prompt, type import numpy followed by the Enter key. If no error messages appear, then your installation of NumPy was successful.

  • At the Python >>> prompt, type import pygame followed by the Enter key. If no error messages appear, then your installation of PyGame was successful.

  • At the Python >>> prompt, type exit() followed by the Enter key to exit Python.

  • In the Terminal window issue the command idle3. If an IDLE window appears, then you have installed IDLE properly. Close the IDLE window.
  • Close the Command Prompt window.

IMPORTANT: When running the Python programs associated with this booksite, do not issue the python command. Instead issue the python3 command. The former command runs the Python 2 compiler/interpreter that is bundled with Mac OS X; the latter command runs the Python 3 compiler/interpreter that you installed by following the instructons on this page.

Downloading and Installing the Booksite Library

Perform these steps to download and install the booksite library:

  • Use your Web browser to download this introcs-1.0.zip file to your /Users/yourusername/Downloads directory.

  • In the Finder, double click on /Users/yourusername/Downloads/introcs-1.0.zip to unzip the file, thus creating a directory named /Users/yourusername/Downloads/introcs-1.0. (It's OK to delete the /Users/yourusername/Downloads/introcs-1.0.zip file after you have unzipped it.)

  • Open a Terminal window.

  • At any time the Terminal application has a working directory. Initially the working directory is /Users/yourusername. In the Terminal window issue the cd Downloads command to change your working directory to /Users/yourusername/Downloads, and then issue the cd introcs-1.0 command to change your working directory to /Users/yourusername/Downloads/introcs-1.0. (Incidentally, the cd . command changes your working directory to the 'parent' of the current working directory.)

  • Issue the ls command to display the names of all files in your working directory. Make sure that a file named setup.py is in your working directory.

  • Issue the python3 setup.py install --user command. The computer copies the files defining the booksite modules to a directory where Python can find them, and writes status messages to your Terminal window to indicate its progress.

Perform these steps to test your installation of the booksite library:

  • In the Terminal window issue the python3 command.

  • At the Python >>> prompt, type the statement import stdio followed by the Enter key. If Python generates no error messages, then you have installed the booksite library properly.

  • At the Python >>> prompt, type exit() followed by the Enter key to exit Python.

  • Close the Terminal window.


Configuring IDLE

So far you've downloaded and installed all of the software that you'll need. You should perform one more step before creating your first program: configure the IDLE programming environment. Follow these instructions:

  • Open a Terminal window.

  • In the Terminal window issue the command idle3 to launch IDLE.

  • Click on the Python → Preferences.. menu item.

  • Click on the General tab.

  • Click on the Open Edit Window radio button.

  • Click on the Ok button.

  • Close the IDLE window.

  • Close the Terminal window.


Composing Your First Program

Having installed Python, the Python standard libraries, IDLE, Tkinter, NumPy, Pygame, and the booksite libraries, and having configured IDLE, you are ready to compose your first Python program. Perform these instructions:

  • Using the Mac Finder, create a directory named /Users/yourusername/hello.

  • Open a Terminal window.

  • Issue the cd hello command to make the /Users/yourusername/hello directory your working directory.

  • Issue the command idle3 & to launch IDLE. Note the trailing ampersand. The trailing ampersand tells the computer to run the idle3 program in the background, thereby leaving your Terminal application free to handle additional commands while IDLE is running.

  • In IDLE, type the four-line Python program helloworld.py exactly as it appears below. Use the arrow keys, mouse, or touchpad to move within the text that you have typed. Use the Delete key to delete text. Be careful; the smallest typing mistake might cause the program to fail.

  • When you are finished typing, in IDLE click on the File → Save.. menu item to save the Python program. Save it in a file named helloworld.py in the directory /Users/yourusername/hello. The file name is case sensitive, so make sure you use all lowercase letters.


Running Your First Program

The final step is to run your program. It is possible to run some Python programs from within IDLE, but you should run the programs associated with this booksite directly from a Terminal window. To do that, perform these steps:

  • Within the same Terminal window, issue the ls command to display the names of all files in the working directory. Confirm that the working directory contains your helloworld.py file.

  • Issue the python3 helloworld.py command to run your program. If the computer writes 'Hello, World' to the Terminal window, then the execution of your helloworld.py program was successful. If the computer instead writes error messages, then use IDLE to correct your program, and issue the python3 helloworld.py command again. Repeat until your program runs successfully. If your program runs successfully the first time you try, then intentionally introduce an error into your program, just so you get some experience with correcting errors.

  • Close the IDLE window.

  • Close the Terminal window.

You now have installed and configured a reasonable Python environment, and have used it to compose and run a Python program. Congratulations! You are a Python programmer!


Downloading the Booksite Example Programs (optional)

We recommend that you download the booksite example programs, that is, the example Python programs that are presented incrementally throughout the booksite. Having done so, you can run those programs to help you learn about them. Perform these instructions:

  • Use your Web browser to download this introcs-python.zip file to your /Users/yourusername/Downloads directory.

  • In the Mac Finder, double-click on /Users/yourusername/Downloads/introcs-python.zip to unzip the file, thus creating the /Users/yourusername/Downloads/introcs-python directory containing the booksite example programs. (It's OK to delete the /Users/yourusername/Downloads/introcs-python.zip file after you have unzipped it.)

Then perform these steps to test your download of the booksite example programs:

Python Program For Matrix Transpose

  • Open a Terminal window.

  • Issue the cd Downloads and cd introcs-python commands to make /Users/yourusername/Downloads/introcs-python your working directory.

  • Issue the ls command. Confirm that the working directory contains a file named bouncingball.py.

  • Issue the python3 bouncingball.py command. If Python launches a stddraw window showing an animated bouncing ball, then your download of the booksite example programs was successful.

  • Close the stddraw window.

  • Close the Terminal window.


Downloading the Booksite Example Data (optional)

We recommend that you download the booksite example data, that is, the data files used by the booksite example programs that are presented incrementally throughout the booksite. Perform these instructions:

  • Use your Web browser to download this introcs-data.zip file to your /Users/yourusername/Downloads directory.

  • In the Finder, double-click on /Users/yourusername/Downloads/introcs-data.zip to unzip the file, thus creating the /Users/yourusername/Downloads/introcs-data directory containing the booksite example data files. (It's OK to delete the /Users/yourusername/Downloads/introcs-data.zip file after you have unzipped it.)


Downloading the Booksite Library: Part 2 (optional)

Previously on this page we described how to download and install the booksite library so Python can find it. Now we describe how to download the booksite library so you can find it — for the sake of studying the code that implements it, should you so desire. Perform these instructions:

  • Use your Web browser to download this stdlib-python.zip file to your /Users/yourusername/Downloads directory.

  • In the Mac Finder, double-click on /Users/yourusername/Downloads/stdlib-python.zip to unzip the file, thus creating the /Users/yourusername/Downloads/stdlib-python directory containing the booksite library. (It's OK to delete the /Users/yourusername/Downloads/stdlib-python.zip file after you have unzipped it.)

We invite you to study the code that implements the booksite library. But don't be concerned if some of the code is cryptic. The code that implements the booksite library uses some features of Python that are beyond the scope of the textbook and this booksite.


Q & A

Q. Why do I get the error ImportError: No module named stdio when I issue the command python program_that_uses_stdio.py?

A. You must issue the command python3 program_that_uses_stdio.py, as described above.

Q. I downloaded files using my browser, but can't find them. Where are they?

A. Many browsers by default place downloaded files in the directory /Users/yourusername/Downloads.

Q. How do I break out of an infinite loop when running my program from the Terminal application?

A. Type Ctrl-c. That is, while pressing the Ctrl key, type the c key.

Q. Must I use IDLE to create my Python programs? Can I use some other text editor?

A. You need not use IDLE to create your Python programs; it is fine to use some other text editor. For example, it is reasonable to use the TextEdit editor that is bundled with Mac OS X. However if you do use some other text editor, then make sure you change its settings so it (1) uses a four-space indentation scheme, and (2) indents using spaces instead of tabs. The Wikipedia Comparison of text editors page provides summary descriptions of many text editors.
