Variables vs. Constants: Key Concepts in Python

This lesson covers variables and constants. Variables, like changing a country name, can hold varying values, while constants, such as "hello world" or 22, remain fixed. We also discuss naming rules for variables: they must start with a letter or underscore, can't begin with a number, and are case-sensitive. The lesson emphasizes the importance of meaningful variable names and concludes with a distinction between variables and constants, setting up future lessons on data types.
