Modify the condition in the outer loop so the turtle drawing has two “peaks” as shown, instead of one. No other change to the code needs to be made.

#   a114_nested_loops_4.py
import time
import turtle as trtl

painter = trtl.Turtle()
painter.penup()
painter.goto(-200, 0)
painter.pendown()

x = -200
y = 0
move_x = 1
move_y = 1
while x < 200:
    while y < 100:
        x = x + move_x
        y = y + move_y
        painter.goto(x, y)
    move_y = -1

    while y > 0:
        x = x + move_x
        y = y + move_y
        painter.goto(x, y)
    move_y = 1
# print("dd")
# time.sleep(10)
x = -200
y = 0
move_x = 1
move_y = -1  # 初始y方向改为向下
painter.penup()
painter.goto(-200, 0)
painter.pendown()
while x < 200:
    while y > -100:  # 变为负值
        x = x + move_x
        y = y + move_y
        print("上:", x, y)
        painter.goto(x, y)
    move_y = 1  # 现在向上移动

    while y < 0:
        x = x + move_x
        y = y + move_y
        print("下:", x, y)
        painter.goto(x, y)
    move_y = -1  # 恢复向下的方向


wn = trtl.Screen()
wn.mainloop()
