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 = 13

while True:
    guess = int(input('请输入一个数量：'))
    if guess > myNumber:
        print('输入的数量过大')
    elif guess < myNumber:
        print('输入的数量过小')
    else:
        print('输入的数量正确')
        break

>>> import turtle
>>> turtle.circle(50,steps=6)
>>> turtle.color('yellow')
>>> turtle.circle(60,steps=6)
>>> turtle.color('red')
>>> turtle.circle(70,steps=6)
>>> turtle.color('green')
>>> turtle.circle(80)

>>> turtle.reset()
>>> turtle.circle(60)
>>> turtle.circle(70)
>>> turtle.circle(90)
>>> turtle.circle(110)

>>> turtle.circle(60)
>>> turtle.up()
>>> turtle.goto(0,-50)
>>> turtle.down()
>>> turtle.circle(120)
