Variables and Data Types

Understanding variables and data types in Python is crucial for programming. Variables serve as names that reference values stored in memory, which can be of various data types such as integers, floats, strings, booleans, and None. It is also important to note the proper syntax for creating variables and performing type conversions using built-in functions.
