Track 13 · Lesson 10 of 12

Readable code

Write code people can understand and change: clear names, small functions, named constants, no duplication, useful docstrings and PEP 8 layout.

You will be able to

• Choose names that say what a value holds or what a function does
• Replace magic numbers with named constants
• Split a function that does several jobs into small functions with one job each
• Write docstrings that explain what a function does, and comments that explain why
• Follow the basic PEP 8 layout conventions
