程序执行流程/布尔类型与布尔：运算猜数字游戏；库的使用：turtle

myNumber = 12

while True:
    guess = int(input('请输入一个数字'))
    if guess > myNumber :
        print('太大了')
    elif guess < myNumber:
        print('太小啦')
    else:
        print('答对了！')
        break

>>> import turtle
>>> turtle.circle(200)
>>> turtle.circle(50)
>>> 

 

>>> import turtle
>>> turtle.up()
>>> turtle.goto(0,-200)
>>> turtle.down()
>>> turtle.circle(200)
>>> turtle.up()
>>> turtle.goto(0,-150)
>>> turtle.down()
>>> turtle.circle(150)
>>> turtle.up()
>>> turtle.goto(0,-100)
>>> turtle.down()
>>> turtle.circle(100)
>>> turtle.up()
>>> turtle.goto(0,-50)
>>> turtle.down()
>>> turtle.circle(50)
