使用pythonturtle绘制n条边的多边形

Question

我是 python 和海龟的新手，希望得到一些帮助。 我正在尝试创建一个程序，该程序接受多条边的输入，然后绘制具有该边数的正多边形。然而，它要么产生 TimeLimitError，要么只是画一条直线。

这是我所拥有的：

sides = int(input("How many sides would you like? "))
angle = sides / 360

import turtle
for count in range(sides):
  turtle.fd(50)
  turtle.lt(angle)

但这就是它不断生产的：

How many sides would you like?  5
TimeLimitError: Program exceeded run time limit. on line 1

Answer 1

您应该将 360 除以边数，而不是相反。

angle = 360 / sides

Answer 2

谢谢您的代码。我稍微改变了它。它没有被用作测试的答案。 （这是在 Grok:Blockly Playground 上完成的）我将在下面发布：

from turtle import *

Fill_colour = input('Fill colour?' + ' ')
left_or_right_ = input('Left or right?' + ' ')
Side_Length = int(input('Length?' + ' '))
Sides = int(input('Sides?' + ' '))
angle = 360 / Sides
PEN_Size = int(input('Pen size?' + ' '))
pensize(PEN_Size)
fillcolor(Fill_colour)
begin_fill()
if left_or_right_ == 'left':
  for count in range(int(Sides)):
    forward(Side_Length)
    left(angle)
else:
  for count2 in range(int(Sides)):
    forward(Side_Length)
    right(angle)
end_fill()
