Python: Call method by instance object: “missing 1 required positional argument: 'self'” [duplicate]

Answer 1

The statement:

k = Class2

Is actually assigning the variable k to the class itself, which is a type object. Remember, in Python everything is an object: classes are simply type objects.

>>> class Class2: pass
...
>>> k = Class2
>>> type(k)
>>> 

What you want is an instance of Class2. For that you must call Class2's constructor:

k = Class2()
