class method with no arguments produces TypeError

Question

This code:

class testclass:
    def __init__(self,x,y):
        self.x = x
        self.y = y
        self.test()

    def test():
        print(\'test\')

i         


        

Answer 1

Pass self to your test method:

def test(self):
    print('test')

You need to do this because Python explicitly passes a parameter referring to the instantiated object as the first parameter. It shouldn't be omitted, even if there are no arguments to the method (because of the error specified).
