Readable Python Code

Working code is only the beginning. This Block shows you how to make Python easier for people to understand by choosing descriptive names, formatting code consistently, and writing comments that add useful context. You will clean up working scripts while keeping their behavior unchanged.

What you will learn:

• Choose clear names for variables, functions, loop variables, and booleans
• Avoid vague, cryptic, or unnecessarily long names
• Use consistent spacing, indentation, blank lines, and line wrapping
• Write comments that explain reasons and important assumptions
• Remove redundant, outdated, and commented-out code
• Check that style improvements do not change program behavior

Build simple habits that make your code easier to scan, understand, and safely change—for other developers and for future-you.
