如何在函数之间传递变量[关闭]

Question

所以这个程序让我可以制作一个可定制的简笔画。我对 python 很陌生，这是我在学校计算机科学之外的第一个大项目。由于身体手臂的坐标在不同的地方结束，我需要来自 bodyfunc、short、medium 和 long 的坐标。该程序有效，但由于某种原因，它没有获取值并将其传递给我的尾部/附件函数。请你看看我的程序并帮助我！

import turtle


#Head
def headfunc(headtype, headcolor, headpensize):
    head=turtle.Turtle()
    head.color(headcolor)
    head.pensize(headpensize)
    if headtype=="square":
        wn = turtle.Screen()
        head.penup()
        head.left(90)
        head.forward(200)
        head.pendown()
        head.left(90)
        head.forward(50)
        head.right(90)
        head.forward(100)

Answer 1

您没有捕获返回值。您需要执行以下操作：

endbody, endarm_x, endarm_y = bodyfunc(bodytype,bodycolor, bodypensize, endbody, endarm_x, endarm_y)

但看起来您来自 bodyfunc 的返回类型不一致，因此这可能会给您带来其他问题。

Answer 2

我认为创建一个类会为你提供最好的服务。

class stickfigure(object):
  def __init__(self):
    self.headtype=input("Enter head(square,round,diamond)")
    self.headcolor=input("Head Color?:Red,white,black,gray,brown,gold,purple,blue,cyan")
    # you get the idea.

这样，您想要保留的值就是您创建的每个简笔画的成员。
