I would strongly consider breaking up your logic into smaller, readable methods. You also don’t need to store the numbers as fields. I.e. Remove this whole block of code… double num1, num2, prod1; double num3, num4, prod2; double num5, num6, prod3; double num7, num8, prod4; double num9, num10, prod5; double grandt = prod1 + prod2 … Read more

In the method h(), the while forms an infinite loop if the atk!=10. so you need to specify an exit condition there to break the loop; you can use like this: public void h() { while (Atk != 10) { this.Atk = random.Next(11); } Console.WriteLine(Atk); } Now you will get a random number between 0 … Read more
There is not (much) difference between def chain_for(*a): and def __init__(self, *a):. Hence, a very crude way to implement this can be: class chain_for: def __init__(self, *lists): self.lists = iter(lists) self.c = iter(next(self.lists)) def __iter__(self): while True: try: yield next(self.c) except StopIteration: try: self.c = iter(next(self.lists)) except StopIteration: break yield next(self.c) chain = chain_for([1, 2], … Read more
