Define functions with defUse parameters and returnDefault argumentsUnderstand scope📚 Quick Recap
🎯 What you'll learn: How to define reusable code blocks with def. Parameters vs arguments, default values, *args and **kwargs, return values, multiple returns. Variable scope — the LEGB rule. Lambda functions. Docstrings. And the most important principle in programming: Don't Repeat Yourself (DRY).
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1Functions are defined with:
2return does what?
3def f(x=3) means x is:
4A function with no return gives:
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5Define with the keyword .
6Values are sent back with .
7Write square(n) returning n*n.
8What does print(square(4)) show?
9Write greet(name) printing Hello .
🚀 Section C · Challenge ● CHALLENGE 5
