In Python, casting refers to the process of converting one data type to another. It's essentially changing a variable from one type (e.g., integer) to another type (e.g., string or float). This is often necessary when you need to perform operations that require specific data types.
Python provides built-in functions to cast data:
Casting to Integer
Casting to Float
Casting to String
Casting to List
Implicit / Explicit Casting
Implicit Casting (also called automatic casting): This happens automatically when Python is able to safely convert one type to another (usually from a smaller type to a larger one, like from an int to a float).
Explicit Casting: This is when you explicitly convert a type using functions like int ( ), float ( ), str ( ), etc.
Casting is a useful concept, especially when dealing with user input, file reading, or working with external APIs that return data in various formats.
