Now you will run the following lines of code then you will not get the error.
class MyClass: def f1(self): self.some_attribute = 10

- You may have forget to include the self as the parameted to the function inside the class.
- Using the self outside the class . It is not allowed in oops concept.
- You may also get the error when you are using the self method without creating instance of the class.
