    Error due to the fact that you pass self.var as an argument to the function. If you want to access the var variable that you defined in the class constructor, then you do not need to pass it to other methods of the class as a separate argument - you will have access to it through self , which is the first argument of the method. Try this:

     class Class(): def __init__(self, var): self.var = var def method(self, var2): return self.var + var2 obj = Class(333) print(obj.method(111)) print(obj.var)

    The result is:

     444 333
    • Later, I want to pass an argument to the method. Therefore, I need to specify it. - Infidus
    • Completed the answer by adding an argument. - Andrey
