同心圆代码会比我输入多一个圆
Concentric circles code will give me one more circle than I input
我的同心圆代码有效,但是当我输入我需要的圆数时,它会比我想要的多一个圆。例如,如果我输入 7 个圆圈,它会给我 8 个,但它只会超过 6 个圆圈。我想知道我的代码有什么问题以及为什么会这样。谢谢。
我的密码是
if r>=50 or r<=200: #if radius is in range, draw circles
for c in range (r, 1, int(-r/num_circles)):
turtle.fillcolor(random.random(),random.random(),\
random.random()) #circles will be a random color
turtle.begin_fill()
turtle.circle(c)
turtle.penup()
turtle.left(90) #concentric
turtle.forward(r/num_circles)
turtle.right(90)
turtle.pendown()
turtle.end_fill()
turtle.hideturtle()
time.sleep(5)
turtle.clear() #clears screen
将您的 for
循环 for c in range (r, 1, int(-r/num_circles))
更改为 for c in range (r, int(r/num_circles), int(-r/num_circles))
以便它可以达到最小值而不是 1。
