Learn Python for Data

Resources to learn and use the Open Source Programming Environment Python for Data Science.

Text Editors v. Integrated Development Environments (IDEs)

While Python code can be run from directly from the Python shell, the command line (Windows), or terminal (OS X), this is impractical for data scientists. In order to properly manage their projects, researchers using Python will not only need to be able to save their Python code, but will often be tasked with coding programs sometimes hundreds of lines (or more) long. Text editors and integrated development environments (IDEs) offer programmers a way to write, save, edit, and execute their programs long term.

Text Editors v. IDEs: What's the Difference?

Text Editors:
  • Programs that allow users to write and save code in a variety of languages.
  • Many text editors are open source (free), and provide advanced features like syntax highlighting, auto-completion, and the like.
  • By default, however, text editors do not allow you to run your code.
  • You will have to use an external compiler in order to run the code.
  • Fortunately, though, many of the more popular text editors will allow you to run your code by installing add-ons.
  • Similar to text editors in the sense that they are also programs that allow you to write and save your code.
  • The big difference is that IDEs will compile your code directly within the program without installing any additional add-ons.
  • In other words, IDEs will allow you to immediately run and/or debug your programs from within the application itself.
  • You do not need to launch an external compiler, such as the command line or terminal, to execute code in your IDE.
  • This can make your workflow easier by limiting the number of windows and programs you need to navigate on your computer.
  • While there are open source IDEs, some of the best IDEs require a paid license.
