1) methods are just functions that happen defined in a class, and need to be callable either as bound methods with implicit self passing or as plain functions with explicit self passing 2) making classmethod s and staticmethod s means you want to be able to rename and omit self respectively. 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 In the body of the method and got a nameerror, consider how can. The self keyword in python is analogous to this keyword in c++ / java / c#
In python 2 it is done implicitly by the compiler (yes python does compilation internally). In php 5, what is the difference between using self and $this Technically both self and this are used for the same thing They are used to access the variable associated with the current instance Only difference is, you have to include self explicitly as first parameter to an instance method in python, whereas this is not the case with java Moreover, the name self can be anything.
Why is cls sometimes used instead of self as an argument in python classes The reason was an ssl certificate problem To answer this question, you need to have at least 10 reputation on this site (not counting the ) In python, every normal method is forced to accept a parameter commonly named self This is how python methods interact with a class's state You are allowed to rename this parameter whatever you please
But it will always have the same value:
