Knowledge
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.

Key Concepts
-
Term: Variable
Definition: A variable is a name that refers to a value stored in the computer’s memory, allowing for data storage, retrieval, and manipulation.
-
Term: Data Types
Definition: The classification of data items in Python which includes int, float, str, bool, and None.
-
Term: Type Conversion
Definition: The process of converting a value from one data type to another using built-in functions like int(), float(), and str().
-
Term: Syntax Rules for Variable Names
Definition: Specific conventions to follow when naming variables, such as starting with a letter or underscore, being case-sensitive, and not using Python keywords.
