unbound method f() must be called with fibo_ instance as first argument (got classobj instance instead)

Question

In Python, I\'m trying to run a method in a class and I get an error:

Traceback (most recent call last):
  File \"C:\\Users\\domenico\\Desktop\\py\\main.py\"         


        

Answer 1

In Python 2 (3 has different syntax):

What if you can't instantiate your Parent class before you need to call one of its methods?

Use super(ChildClass, self).method() to access parent methods.

class ParentClass(object):
    def method_to_call(self, arg_1):
        print arg_1

class ChildClass(ParentClass):
    def do_thing(self):
        super(ChildClass, self).method_to_call('my arg')
