mu-editor

Mu is a Python code editor for beginner programmers. This means Mu makes it very easy to create, run, and revise your Python programs as you learn to code in Python.

Mu is very simple and easy to understand. As you type code, Mu will change the color of the text to help you read the code. On the left side, there is a column containing the line numbers for your file. These are useful for when Python reports errors.
