How to check if a variable is a number in Python

You can check if a variable is an integer using the type() function, passing the variable as an argument, and then comparing the result to the int class:

age = 1
type(age) == int #True

Or using isinstance(), passing 2 arguments: the variable, and the int class:

age = 1
isinstance(age, int) #True

You can check if the number is a floating point number by comparing it to float instead of int:

fraction = 0.1
type(fraction) == float #True
