In Python, variables are created when you assign a value to it. There is no declaration keyword like let or var.

Variable Assignment and Types

Python has dynamic typing: you do not need to declare variable types.

Common built-in types: int, float, str, bool.

Use type(variable) to inspect what data type an object holds.

Use casting functions: int(), float(), str() to convert between types.
