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. So, in the first method self specifies that python should use the variable (attribute), that belongs to the class object we created, not a global one (outside the class).
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. Say i want to implement a method that pretty prints the struct to stdout, should i take &self I guess self also works
If you use self (or &mut self) the method will likely still compile, but it can only be used in more restricted situations. Why is cls sometimes used instead of self as an argument in python classes 6 self refers to the current instance of bank When you create a new bank, and call create_atm on it, self will be implicitly passed by python, and will refer to the bank you created. __iter__(self) however, upon following up the link to iterator types in the python reference manual, there are no examples given of how to implement your own Can someone post a snippet (or link to a resource), that shows how to do this
The container i am writing, is a map (i.e Stores values by unique keys) Dicts can be iterated like this: In python to call inner class method you should write self Means that search class for this method but you don't use self when you call say_hi () in say_something method and this cause to call say_hi function that declared outside of class. It's named my ca, and should be put in the ca store for the current user
