Python:Error calling class variable in a staticmethod

Question

I am trying to call a class variable within a staticmethod, but when I called I am getting an error "hello" is not defined. any advise ?

class hello: random1 = [] @staticmethod def sub(x): hello.random1.append(x -1) sub.__func__(2) if __name__ == "__main__": print(hello.random1)

Yes, because the class hello doesn't exist when it's class body is being executed — juanpa.arrivillaga

hello doesn't exist as a global name until you dedent out of the class definition (at which point the class is created and assigned to the global name hello). Change the code to:

class hello: random1 = [] @staticmethod def sub(x): hello.random1.append(x -1) hello.sub(2)

so sub is invoked after hello exists, and it will work.
