Style Guide

Readable beginner code is a course goal, not decoration. Use style choices that help another person follow the program.

Naming

• Prefer total_cost over tc.
• Use singular names for one value and plural names for lists when practical.
• Match the name to the purpose, not merely the type.

Layout

• Use blank lines to separate meaningful sections.
• Keep indentation consistent.
• Avoid crowding several unrelated ideas onto one line.

Functions

• Give each function one main job.
• Choose parameter names that reveal their meaning.
• Return values when later code needs a result.

Comments

Comments should explain purpose or a non-obvious choice. They should not repeat what a straightforward line of code already says.
