TypeError: setcoords() missing 1 required positional argument: 'coords1'

Question

full code with error message

我正在尝试 class 来绘制三角形，但显然在第 29 行中有一个我无法解决的问题。我在这里阅读了其他一些问题，但它们主要是关于 'self' 这不是我的错误

 def setcoords(self,coords1):
    self.coords=coords1


triangle.setcoords(((100,100),(150,200),(200,100)))
print (triangle.givecoords())
triangle.setcolor((0,255,0))
triangle.setvisible(True)
triangle.draw()

Answer 1

您必须创建一个 Instance Objects:

my_triangle = triangle()
my_triangle.setcoords(((100,100),(150,200),(200,100)))

Class Names should normally use the CapWords convention and have a constructor (__init__):

class Triangle:
    def __init__(self, coords1):
        self.coords = coords1
    # [...] 
 
my_triangle = Triangle([(100,100),(150,200),(200,100)])
