繪製漸變的圓input

描述

利用turtle庫的circle(50)函數能夠畫半徑爲50的圓，circle(50,steps=n)能夠畫半徑爲50的圓的內接正n邊形，利用這個方法繪製示例中的圖形，設置畫筆爲藍色並用黃色填充圖形。n由用戶輸入，要求n>=3且小於10。(注意：最後一個必須是圓，不能是正多邊形)‪‬‪‬‪‬‪‬‪‬‮‬‪‬‮‬‪‬‪‬‪‬‪‬‪‬‮‬‫‬‭‬‪‬‪‬‪‬‪‬‪‬‮‬‫‬‫‬‪‬‪‬‪‬‪‬‪‬‮‬‭‬‫‬‪‬‪‬‪‬‪‬‪‬‮‬‫‬‫‬‪‬‪‬‪‬‪‬‪‬‮‬‫‬‪‬it

疊加三角形

繪製奧運五環

 1 #五環
 2 import turtle     #引用turtle庫
 3 turtle.pensize(10)   #設置畫筆大小
 4 coordA=[-110,0,110,-55,55]    #各個圓X軸座標
 5 coordB=[-25,-25,-25,-75,-75]   #各個圓的Y座標
 6 colors=["red","blue","green","yellow","black"]
 7 for i in range(5):
 8     turtle.pencolor(colors[i])
 9     turtle.penup() 
10     turtle.goto(coordA[i],coordB[i])
11     turtle.pendown()
12     turtle.circle(45)
13 turtle.hideturtle()  #隱藏畫筆

五環

啊~五環！你比六環少一環~

繪製八卦陣

 1 #八卦陣
 2 import turtle
 3 turtle.pensize(5)                  #畫筆大小
 4 turtle.penup()
 5 turtle.goto(0,120)
 6 turtle.pendown()
 7 
 8 turtle.color("black","black")
 9 turtle.begin_fill()
10 turtle.circle(-120,180)
11 turtle.circle(-60,180)
12 turtle.circle(60,180)
13 turtle.end_fill()

28 turtle.circle(20)
29 turtle.end_fill()
30 
31 turtle.hideturtle()                #隱藏畫筆

八卦陣

這裏咱們取大圓的半徑爲120，中圓天然是它的一半，小圓咱們取中圓的三分之一。這樣之後，各個點的座標都出來了

天靈靈，地靈靈~
