Examples of getattr() method in Python

Example 1:How getattr() works in Python?

class Person:
    age = 30
    name = "James"
pers = Person()
print('The age is:', getattr(pers, "age"))
print('The age is:', pers.age)


The age is: 30
The age is: 30

Example 2:getattr() when named attribute is not found

class Person:
    age = 30
    name = "James"
pers = Person()

# when default value is provided
print('The sex is:', getattr(pers, 'sex', 'Male'))

# when no default value is provided
print('The sex is:', getattr(pers, 'sex'))


The sex is: Male
AttributeError: 'Person' object has no attribute 'sex'

Example 3:getattr() raising attribute error

class GfG :
    name = "GeeksforGeeks"
    age = 24
# initializing object
obj = GfG()
# use of getattr
print("The name is " + getattr(obj,'name'))
# use of getattr with default
print("Description is " + getattr(obj, 'description' , 'CS Portal'))
# use of getattr without default
print("Motto is " + getattr(obj, 'motto'))


The name is GeeksforGeeks
Description is CS Portal

AttributeError: GfG instance has no attribute 'motto'
