Python setattr() and getattr() goes hand-in-hand. As we have already seen what getattr() does; The setattr() function is used to assign a new value to an object/instance attribute.
Syntax
setattr(object, name, value)
where,
value = value to be set for the attribute
Example
# Python program to illustrate setattr() function
class Details:
   name = 'Sam'
   age = 24
# Create an object of the class
d = Details()
print('Name before modification:', d.name)
print('Age before modification:', d.age)
setattr(d, 'name', 'Timmy')
setattr(d, 'age', 27)
print('Name after modification:', d.name)
print('Age after modification:', d.age)
Output
Name before modification: Sam
Age before modification: 24
Name after modification: Timmy
Age after modification: 27
