Bugs are mistakes in programs that cause them to behave differently than intended.

Debugging is the process of finding and fixing those bugs.

1.1. Print Statement Debugging

the output generated helps diagnose issues within the program.

is a tool built into VS Code, which will walk through the program step-by-step.

by talking through the code out loud, we might realize the mistake.
