In this course you will write and debug programs with functions, while learning how to structure code that scales to solving large, complex problems.

Through a sequence of cryptography-themed programming challenges, you will explore how to encapsulate logic and processes in functions. More advanced topics like multiple inputs, function composition, and function dependency are introduced gradually.

Decode secret messages using Python functions.
