I want to add method1 to my class from outside of my class. Also I want to call method1 from inside of my class in order to changing the 'homework' to 0
def method1(self): print("Processing.....") print("Done :D") self.homework = 0 class S: homework = 10 def homeworkremover(self): S.method1 = method1 S.method1() a = S() print(a.homeworkremover()) But I've received an error code:
TypeError: method1() missing 1 required positional argument: 'self' Can you help me out pls?
The example seems quite contrived, I can't quite see the use of it in its current form (adding a new method on a class from within a method that is being executed on an instance of the class).
But to make it work nevertheless, simply replace:
Sss.method1() with
self.method1() since the added method is intended as an instance method and not a class method.
On a side note, instead of
Sss.method1 = method1 it might be better to use:
self.__class__.method1 = method1 (less dependent on the class name, and works better as well in class inheritance scenarios)
