Python入门_绘制多个五角形_turtle
汇率兑换的程序已经实现了;
优化: 运行更快; 更简洁
1. turtel 库:
2. 绘图坐标体系:
https://docs.python.org/3.0/library/turtle.html
import turtle
def draw_wujiao(size):
count = 1
while count <= 5:
turtle.forward(size)
turtle.right(144)
count = count + 1
def main():
#循环的魅力,可以循环多次实现相同的操作
turtle.penup()
turtle.backward(200)
turtle.pendown()
turtle.pensize(2)
turtle.pencolor('red')
size = 50
while size <= 60:
draw_wujiao(size)
size += 10
turtle.exitonclick()
if __name__ == '__main__':
main()
3.递归函数:调用自身函数的函数
