How to Call a method of class having no argument

[dataplumber]

Methods need to be declared with self as the first parameter, e.g.

 class Foo: def bar(self): pass f = Foo() f.bar() 

Yes, with self as argument it is working. That being said, Is it necessary to have all the class methods should have at least 1 argument (self) in our case. Can't we have no arguments ?

Thank you. That Answers my question.
