He only used the word "function", but his pseudocode used a method. Either way, one shouldn't normally use magic methods directly.

Get bound method by name
Hello group, I'm looking for a Python function but have forgotten it's name. Essentially what I want is: class Foo(): def bar(self): pass x = Foo() y = x.MAGIC("bar") print(y) > So the question is: How is the magic function called which returns me the bound method of a class instance by its name? I know there was a way but just can't remember...
