我用python写了一个乌龟程序,但是有两个问题。
- 对于较大的数量来说,它的速度太慢了,我想知道如何才能加快乌龟的速度。
- 它在完成后冻结,单击时显示“没有响应”
到目前为止,这是我的代码:
import turtle
#Takes user input to decide how many squares are needed
f=int(input("How many squares do you want?"))
c=int(input("What colour would you like? red = 1, blue = 2 and green =3"))
n=int(input("What background colour would you like? red = 1, blue = 2 and green =3"))
i=1
x=65
#Draws the desired number of squares.
while i < f:
i=i+1
x=x*1.05
print ("minimise this window ASAP")
if c==1:
turtle.pencolor("red")
elif c==2:
turtle.pencolor("blue")
elif c==3:
turtle.pencolor("green")
else:
turtle.pencolor("black")
if n==1:
turtle.fillcolor("red")
elif n==2:
turtle.fillcolor("blue")
elif n==3:
turtle.fillcolor("green")
else:
turtle.fillcolor("white")
turtle.bk(x)
turtle.rt(90)
turtle.bk(x)
turtle.rt(90)
turtle.bk(x)
turtle.rt(90)
turtle.bk(x)
turtle.rt(90)
turtle.up()
turtle.rt(9)
turtle.down()
顺便说一句:我使用的是3.2版本!
- Set
turtle.speed("fastest")
.
- Use the
turtle.mainloop()
无需刷新屏幕即可完成工作的功能。
- 禁用屏幕刷新
turtle.tracer(0, 0)
然后最后做turtle.update()
