才发现py自带的这个库[python]import turtle as tt
tr=tt.getturtle()
tr.shape('turtle')
tr.speed('fast')
IN_TIMES = 40
TIMES = 20
for i in range(TIMES):
tr.right(360/TIMES)
tr.forward(200/TIMES)
for j in range(IN_TIMES):
tr.right(360/IN_TIMES)
tr.forward (400/IN_TIMES)
screen = tt.Screen()
screen.exitonclick() [/python]
