I recently learned poo in Java and now I am learning in Python. Is there overload polymorphism(implement methods with equal n ... parameters you hand over to the method, it calls one or the other)? If there is not, what would be the alternative to this?

I'm having a problem implementing operator = overhead on a heap class. Heap& Heap::operator=(const Heap& outro){ ... t is, with the value that h3 was before the call of overload. I hope I've been clear about the problem. Thank you right now.

How does this code work? class MyClass: def __init__(self, *args): self.Input = args def __add__(self, Other): ... ss("Yellow", "Purple", "Cyan") Value3 = Value1 + Value2 print("{0} + {1} = {2}" .format(Value1, Value2, Value3))
