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. Many have proposed to make self a keyword in python, like this in c++ and java This would eliminate the redundant use of explicit self from the formal parameter list in methods. 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. Say i want to implement a method that pretty prints the struct to stdout, should i take &self I guess self also works As you can see, this is exactly a case for &self If you use self (or &mut self) the method will likely still compile, but it can only be used in more restricted situations. The w3c's webappsec working group is starting to look at the issue
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: 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 association bonus) Why is cls sometimes used instead of self as an argument in python classes
