What Does isinstance() Do in Python?
Python’s isinstance() function helps you determine if an object is an instance of a specified class or its superclass, aiding in writing cleaner and more robust code. You use it to confirm that function parameters are of the expected types, allowing you to handle type-related issues preemptively. This tutorial explores how isinstance() works, its use with subclasses, and how it differs from type().
By the end of this tutorial, you’ll understand that:
isinstance()checks if an object is a member of a class or superclass.type()checks an object’s specific class, whileisinstance()considers inheritance.isinstance()correctly identifies instances of subclasses.- There’s an important difference between
isinstance()andtype().
Exploring isinstance() will deepen your understanding of the objects you
