0 the surroundings

Python version ：iii.6.6

one the introduction

recently, my girl-in-law has been looking at her cell phone and the toilet every dark when she has dinner 。

watching and laughing ？WTF？ what are you doing ？

yeah, she's watching captain america ……

this man is more than handsome than me ？……

than i have money ？……

still better than me ？……

the answer is obvious, and i'm sure your optics are wide open 。

that's the problem, as a man ， how can i endure ？ it's a star, it's a fake ， there is no turning back …… i'll give you a cap ……

this article is not an introduction to turtle ， therefore, the basic brush employ of xiao pang is not redundant in this article. interested can leave a message ， i'll write i or a series based on your feedback.

2 in bodily combat

allow's wait at a rendering first ：

anybody who's used turtle knows this ， a brush needs to be lifted and drawn. this is of import to understand ， because computers are rigid, you have to tell them everything yous do ， including the gc.

so as presently as your brush drops, it leaves a mark everywhere it goes 。 if you want a distance you have to go through 「 pen upward 」->「 move the brush 」->「 put pen to paper 」。

so let'southward first encapsulate this action as a function ：

          def setpen(x, y):     #  pen up      t.penup()     #  permit's motion the castor to (x, y)     t.goto(ten, y)     #  put pen to paper      t.pendown()     t.setheading(0)        

at present let'southward depict the shield. if the shield ， watch for the u.s. shield. color is 「 red 」->「 white 」->「 reddish 」->「 bluish 」。

now, at that place'south a fob here, which is that the background color of the filled circle in the back is going to overwrite the groundwork color of the previously drawn circle 。

          def circumvolve(ten, y, r, color):     #  to make sure we draw a circle that is round enough, nosotros set the edges of the circle a lilliputian bit more      n = 36     angle = 360 / north     pi = three.1415926     #  the perimeter      c = 2 * pi * r     #  the length of each side      l = c / north     #  the starting position      start_x = ten - fifty / 2     start_y = y + r     #  motion the brush      setpen(start_x, start_y)     #  i'm gonna go alee and select the brush color      t.pencolor(color)     #  select groundwork colour      t.fillcolor(color)     #  make full      t.begin_fill()     for i in range(northward):         t.forrard(l)         t.right(angle)     t.end_fill()        

and then there'due south the white star in the flick, so i won't comment on that ， because information technology's the same process as drawing circles.

          def five_star(l):     setpen(0, 0)     t.setheading(162)     t.forward(150)     t.setheading(0)     t.fillcolor('WhiteSmoke')     t.begin_fill()     t.hideturtle()     t.penup()     for i in range(5):         t.forward(fifty)         t.right(144)     t.end_fill()        

the main office ：

          def sheild():     circumvolve(0, 0, 300, 'cherry-red')     circle(0, 0, 250, 'white')     circle(0, 0, 200, 'cerise')     circle(0, 0, 150, 'blue')     five_star(284)  if __name__ == '__main__':     sheild()     #  stop turtle      turtle.done()        

3 conclusion

this is an article on drawing in python ， more than interesting 、 fun python app 、 combat is on the planet of knowledge 「 everyone is a pythonista 」。

follow public business relationship 「Python column 」， answer ： the team the shield ， get the total lawmaking ！
