将参数列表传递给类

Question

I am creating a class called Triangle . Within Triangle , it is passed three_points list and two_angles list (ie self.triangle0 = Triangle([1, 2, 3], [20, 30]) )

I am defining

class Triangle(object):

    def __init__(self, three_points, two_angles):
        self.points = three_points
        self.angles = two_angles

Since it is a list I am passing in and not just a single number, do I have to create lists to put the values in or does this just work?

Answer 1

This will work how you have it mocked up. At runtime self.points will be a list containing whatever values you passed in. Same with self.angels. Note that if your list contains objects and not just primitives you may be passing in a pointer in your list and not the actual object.
