用python画猫和老鼠_一个Python游戏：猫和老鼠
写出一个猫和老鼠的游戏。游戏者使用方向键来控制老鼠，使其保持在猫的前方(由计算机控制猫)。保持时间越长，得分越高。
import turtle
import time
boxsize = 200
caught = False
score = 0
# functions that are called on keypresses
def up():
mouse.forward(10)
checkbound()
def left():
mouse.left(45)
def right():
mouse.right(45)
def back():
mouse.backward(10)
checkbound()
def quitTurtles():
window.bye()
# stop the mouse from leaving the square set by box size
def checkbound():
global boxsize
if mouse.xcor() > boxsize:
mouse.goto(boxsize, mouse.ycor())
if mouse.xcor() < -boxsize:
mouse.goto(-boxsize, mouse.ycor())
if mouse.ycor() > boxsize:
mouse.goto(mouse.xcor(), boxsize
