Python class attribute referencing

Question

This is a sample code that i found from one of the python class tutorial.

class MyClass:
    i = 12345
    def f(self):
        return \'hello world\'

print MyC         


        

Answer 1

Always a function is called by its name, which is represented by (). So use MyClass.f()

Answer 2

Create an instance of MyClass first.

test = MyClass()
print test.f()
print MyClass.i

You don't need to create an instance of MyClass for i, because it is a class member, not an instance member.
