A Notebook for Skills on Python Functions

A hands-on Python notebook that teaches core built-in functions by running real code. Includes explanations, examples, exercises, and failure checks. Ideal for beginners who want to actually understand Python instead of copying snippets.

This notebook (in PDF and Jupyter Notebook) teaches essential Python functions through execution, not memorization. Each concept is introduced with clear context, explained in plain language, and reinforced through runnable code and validation checks. The focus is on building correct mental models and avoiding common beginner errors that silently break programs.
