pendown()
for _ in range(5):
    forward(35)
    right(144)
end_fill()

for _ in range(400):
    x = random.randint(-700,700)
    y = random.randint(-700,700)
    edge_len = random.randint(3,4)
    left_angle = random.randint(0,180)
    stars1(x,y,left_angle,edge_len)
penup()

最后星星亮起来那一下感觉还可以，喜欢的家人们可以试一试
最后的效果
