In this article, we’ll look at how to check if an object has an attribute in Python.

How to check if an object has an attribute in Python?

To check if an object has an attribute in Python, we can use the hasattr function.

For instance, we write:

class A:
  property = 'foo'

a = A()  
if hasattr(a, 'property'):
    print(a.property)

We have an A class with the property instance property set to 'foo'.

Then we create a new instance of A.

And then we call hasattr with a and 'property' to check if property property exists in a.

Since this is True, we see 'foo' printed.

To check if an object has an attribute in Python, we can use the hasattr function.
