Question

How does issubclass() function work in Python?

Answer 1

This function returns True if class is a subclass of classinfo.

A class is considered a subclass of itself. We can also pass a tuple of classes as the classinfo argument, in that case, the function will return True if class is a subclass of any of the classes in the tuple.

Since the object is the base class in Python, the function will return True if classinfo is passed as object class.
