Re: [Maya-Python] Using strings as a check in __init__?

True, you don't need to enclose the instantiation in a try except if you don't need to keep executing the program after a bad input, it's fair enough if that's your goal (although I guess you can see my point when I mention it in the first place) Look, It's ok to disagree on styles and all that

Re: [Maya-Python] Using strings as a check in __init__?

Sure you can (although it forces the user to enclose any instantiation on a try except, but it works). I guess my point is that validation is usually done in the constructor and not initialisation, creating an instance just to destroy it later on without doing any work (contributing to solve the

Re: [Maya-Python] Using strings as a check in __init__?

There's a fundamental problem with this in my view, the dounder init method of a class gets executed _after_ the instance (aka self) get created, doing checks there means you basically create an object that can potentially be invalid by passing the wrong thing and that's a problem. You could use

@Justin Truth be told, initially I wrote it as: if self.state == self.STATE_ROOT_SELS: # Run function_A() if self.state == self.STATE_USER_SELS: # Run function_B() There was no `else` and then before posting my thread, I rewrote it to using `if...elif...` but am unsure whether if I should

Re: [Maya-Python] Using strings as a check in __init__?

Most of what I wanted to comment is already covered by Justin and Marcus. Here are my very very minor comments (consider them as extras): 1. self._state instead self.state (~ by convention, self.state should be used only if `state` is public. From your code, and I presume, `state` is not public.

I re-post my message... @Marcus Thanks for the information! Glad to know that I am on track, to be honest, I was not able to find much info online, perhaps my searching skill was not that great in this aspect :p @Justin Thanks for the code. I have decided to use your format for my code. Even

@Marcus Glad to know that I am somewhat on the right track! To be honest, I could not find much info online, either that or I must have been typing it wrongly, unable to get a decent result @Justin Thanks for the code, decided to implement the way that you have mentioned. Another quick

[Maya-Python] Using strings as a check in __init__?

I would like some opinions on the way I am using instance variables in my class as I am not so sure if I am doing it right.. To be honest, this is my first time using parameters in my class __init__.. class HierarchyDialog(QtGui.QDialog): def __init__(self, state, parent=None):
