if instance python code example

Example 1: isinstance python

isinstance(object, classinfo)

# if classinfo is a tuple of type objects (or recursively, other such tuples), return True
# if object is an instance of any of the types. If classinfo is not a type or tuple of types
# and such tuples, a TypeError exception is raised.

Example 2: how to check if a variable in python is a specific data type

isinstance(variable_name, class_name) #eg. isinstance(age, int) will return True

Example 3: isinstance python 3 not running
