Python elif Chains

Sometimes two branches are not enough. This Block shows how to use elif to build clean multi-choice decisions in Python. You will start with simple score and grade examples, then move into menu choices, temperature labels, fallbacks, and common beginner mistakes.

The main idea is simple: Python checks an if / elif / else chain from top to bottom, and the first matching branch wins. Once that clicks, bigger decisions become much easier to read and control.

What you will learn:

• Use elif to add more branches after an if
• Understand why only the first matching branch runs
• Order conditions correctly for ranges like scores and temperatures
• Choose between separate if statements and one elif chain
• Add a final else when your program needs a fallback
• Avoid common mistakes with indentation, branch order, and invalid syntax

By the end, you will be able to write small decision-making programs that choose exactly one result without turning your output into grade soup.
