I’m doing something wrong in the code below. I have a method (update_dictonary) that changes a value or values in a dictionary based on what is specificed in a tuple (new_points).

The following python code is valid and produces the expected result ("1, 2, 3") but it feels wrong somehow: class myClass(): foo = None def myfunc(self): for self.foo in [1, 2, 3]: print(self.foo) return myClass().myfunc() I have not… Read More Are class variables accessed via self used as iterables good practice/pythonic?

I mean something like this: output = [‘ClassA’, ‘ClassB’, ‘FunctionC’] Is it possible? >Solution : Looks like inspect.stack()… Read More Python: How to get all the parent classes and function names in one array within that function
