How to check if a variable is number in Python

Python is a dynamically typed language, meaning that variables can change types during execution. Checking types helps ensure that your code operates correctly with the expected data types and avoids unexpected behavior.

Numeric types in Python include:

• Integer (int) represents whole numbers, positive or negative, without any decimal point.


• Floating-point (float) represents real numbers with a decimal point.


• Complex (complex) represents numbers with a real and imaginary part.
