1. Definition with examples

Data type is a classification that  specifies which type of value a variable can hold. It defines the type of operations that can be performed on that variable and how those values are stored in memory. Data types are essential in programming because they help ensure the correctness and consistency of data manipulation.

Python has a dynamic typing system, which means that you don't need to explicitly declare the data type of a variable when you create it. Instead, Python infers the data type based on the value assigned to the variable.
