getattr

• getattr

It returns the value of the named attribute of an object.

getattr(object, name)

class Person:
    age = 23
    name = "Adam"

person = Person()
getattr(person, 'age')
>>>
23

 

 

When the named attribute is not found, default value is returned.

getattr(object, name, default)

class Person:
    age = 23
    name = "Adam"

person = Person()
getattr(person, 'gender','unknown')
>>>
unknown

The named attribute gender is not present in the class Person. So when calling getattr() with a default value 'unknown', it returns 'unknown'.
