How to know if an object has an attribute in Python

Question

Is there a way in Python to determine if an object has some attribute? For example:

>>> a = SomeClass()
>>> a.someProperty = value
>>         


        

Answer 1

You can use hasattr() or catch AttributeError, but if you really just want the value of the attribute with a default if it isn't there, the best option is just to use getattr():

getattr(a, 'property', 'default value')
