Python 🐍 Variables

This video tutorial covers the basics of variables in Python, including data types such as integers, floats, strings, and booleans. It explains how to use these variables in expressions, the rules for naming them, and how to convert between types. The tutorial also introduces a project involving temperature control, demonstrating how to apply these concepts practically.
