Before you can start writing Python code, you'll need to install Python on your computer. Python can be downloaded for free from the official Python website (python.org), and is available for Windows, Mac, and Linux operating systems.

Once you've downloaded and installed Python, you'll also need a code editor to write and run your Python code. A code editor is a software application that allows you to write and edit code, and can provide helpful features such as syntax highlighting and autocompletion.

There are many code editors available, both free and paid. Some popular options include:

  • Visual Studio Code (free)
  • PyCharm Community Edition (free)
  • Sublime Text (paid)
  • Atom (free)
  • IDLE (included with Python)
In this book, we'll be using Visual Studio Code as our code editor, but you're free to use any code editor you prefer.
Once you've installed Python and a code editor, you're ready to start writing Python code! In the next topic, we'll cover the basics of writing and running your first Python program.
