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).
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. Why is cls sometimes used instead of self as an argument in python classes 6 self refers to the current instance of bank
When implementing a trait, we often use the keyword self, a sample is as follows I want to understand the representation of the many uses of self in this code sample __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:
