The isinstance() function checks if the object (first argument) is an instance or subclass of classinfo class (second argument).
Example

Example 1: How isinstance() works?
Output
True False True
Example 2: Working of isinstance() with Native Types
Output
[1, 2, 3] instance of list? True [1, 2, 3] instance of dict? False [1, 2, 3] instance of dict or list? True 5 instance of list? False 5 instance of int? True
