When do we need (self) in methods??
« on: January 30, 2019, 11:46:48 AM »
So I thought every python function definition needed (self) unless multiple paramters are being specified...what's the rule regarding self??

My __init__(): function does NOT have self, and when I instantiate with Shet() it says takes 0 positional arguments but 1 given. I tried adding a self to the definition, then it says missing 'self'... I can't possibly add anything to Shet() because what would I add-it's not expecting any arguments. what am I to do?? So confused.

Self was one of the things for me that took some time to sink in. As an analogy to understand it better I borrowed this instead of self from Java/JS.
this.name = name instead of self.name = name
where this is presupposed to be a reference to this object in question.
