- oop - Why do you need explicitly have the self argument in a Python . . .
By making the self reference explicit, you're free to refer to any object by that self reference Also, such a way of playing with classes at runtime is harder to do in the more static languages - not that's it's necessarily good or bad It's just that the explicit self allows all this craziness to exist
- What is the purpose of the `self` parameter? Why is it needed?
For a language-agnostic consideration of the design decision, see What is the advantage of having this self pointer mandatory explicit? To close debugging questions where OP omitted a self parameter for a method and got a TypeError, use TypeError: method () takes 1 positional argument but 2 were given instead If OP omitted self in the body of the method and got a NameError, consider How can
- What difference does it make to use self to define a member in a . . .

- How to bypass certificate errors using Microsoft Edge

- Difference between _self, _top, and _parent in the anchor tag target . . .

- Difference between cls and self in Python classes?
Why is cls sometimes used instead of self as an argument in Python classes? For example: class Person: def __init__(self, firstname, lastname): self firstname = firstname self
- Understanding Python super() with __init__() methods
In Python 2, we were required to call super like this with the defining class's name and self, but we'll avoid this from now on because it's redundant, slower (due to the name lookups), and more verbose (so update your Python if you haven't already!):
