Python: Call method by instance object: "missing 1 required positional argument: 'self'"

call_uselessmethod requires that there first be an instance of Class2 before you use it. However, by doing this:

k = Class2

you are not assigning k to an instance of Class2 but rather Class2 itself.

To create an instance of Class2, add () after the class name:

k = Class2()

Now, your code will work because k points to an instance of Class2 like it should.
