In Python you can use setattr to set an attribute on a class. Let's say we have a very simple class like below:

class User:
     def register(self, key, val):
         setattr(self, key, val)

Now if you want to set an attribute called name on User class:

>>> user = User()
 >>> user.register('name', 'alireza')
 >>> user.name
 'alireza'

With a little bit of code you can automatically get data from a source and set dynamic attributes.

#python #setattr
