Installing and Running Python


This section provides an overview of different ways to run Python code, and quickstart guides for:

  1. Choosing a Python platform

  2. Installing and managing Python with Conda

Choosing a Python Platform

There is no single official platform for the Python language. Here we provide a brief rundown of 3 popular platforms:

  1. The terminal,

  2. Jupyter notebooks, and

  3. IDEs (integrated development environments).

Here we hope to provide you with enough information to understand the differences and similarities between each platform, so that you can make the best choice for your work environment and learn along effectively, regardless of your Python platform preference.

In general, it is always best to test your programs in the same environment in which they will be run. The biggest factors to consider when choosing your platform are:

  • What are you already comfortable with?

  • What are the people around you using (peers, coworkers, instructors, etc.)?


For learners who are familiar with basic Linux commands and text editors (such as Vim or Nano), running Python in the terminal is the quickest route straight to learning Python syntax without the covering the bells and whistles of a new platform. If you are running Python on a supercomputer, through an HTTP request or SSH tunneling, you might want to consider learning in the terminal.

Jupyter Notebooks

We highly encourage the use of Jupyter notebooks: a free, open-source, interactive tool running inside a web browser that allows you to run Python code in “cells.” This means that your workflow can alternate between code, output, and even Markdown-formatted explanatory sections that create an easy-to-follow analysis or “computational narrative” from start to finish. Jupyter notebooks are a great option for presentations or learning tools. For these reasons, Jupyter is very popular among scientists. Most lessons in this book will be taught via Jupyter notebooks.

Other IDEs

If you code in other languages, you might already have a favorite IDE that will work just as well in Python. Spyder is a Python specific IDE that comes with the Anaconda download. It is perhaps the most familiar IDE if you are coming from languages such as Matlab that have a language specific platform and display a list of variables. PyCharm and Visual Studio Code are also popular IDEs. Many IDEs offer support for terminal execution, scripts, and Jupyter display. To learn about your specific IDE, visit its official documentation.

We recommend eventually learning how to develop and run Python code in each of these platforms.

Installing and managing Python with Conda

Conda is an open-source, cross-platform, language-agnostic package manager and environment management system that allows you to quickly install, run, and update packages within your work environment(s). Conda is a vital component of the Python ecosystem. Understanding it is important, regardless of the platform you chose to run your Python code.

Python can be run on many different platforms. You may choose where to run Python based on a number of factors. The tutorials in this book will be formatted as Jupyter Notebooks.
