Python Functions Practice Notebook

50 Progressive Questions for High School Students

This notebook introduces Python functions with a high-school level progression.

Learning goals

By the end, students should be able to:

• define and call functions
• use parameters and return values
• use conditionals inside functions
• use loops inside functions
• iterate through strings, lists, and dictionaries
• solve small practical problems using functions
• break a larger problem into smaller reusable parts

Important idea: print() vs return

• Use print() when the goal is only to show output on the screen.
• Use return when the function should send a result back so it can be reused later.

Directions

• Read each question carefully.
• Write the full function in the code cell below each question.
• Test your function using the example calls.
• Do not worry if your solution is different from a classmate's solution, as long as the output is correct.
