I've created a skeleton Point class for points in a 3D space (e.g. with x, y, and z co-ordinates). I want the co-ordinates to be integers and for any other input value to be refused. That part works fine. I just can't figure out a way to have the class constructor refuse to initialize an object if any of the three inital values is not an integer. How do I do that? Here's my code so far:
class Point: def __init__(self, x, y, z): self.x = x self.y = y self.z = z @property def x(self): return self.__x @x.setter def x(self, a): if isinstance(a, int): self.__x = a else: print("x must be an integer") return None @property def y(self): return self.__y @y.setter def y(self, b): if isinstance(b, int): self.__y = b else: print("y must be an integer") return None @property def z(self): return self.__z @z.setter def z(self, c): if isinstance(c, int): self.__z = c else: print("z must be an integer") return None
