Type

Definition

A type describes the kind of value that a variable can hold, such as integers, floating-point numbers, strings, and more. Python uses dynamic typing, meaning that the type of a variable is determined at runtime.

1. Common types in Python include int, float, str, list, tuple, dict, and bool.
2. The type() function in Python returns the type of an object.
3. Unlike statically-typed languages, Python does not require explicit declaration of variable types.
4. Type conversion or casting can be done using functions like int(), float(), str(), etc.
5. Python supports type annotations for better code readability and error checking.
