1、python通过turtle画一个圆import turtle as tt.penup()t.goto(-150,120)t.pendown()t.pensize(3)t.pencolor("blue")t.circle(50)
2、复制画一个圆的代码，到画五环，思路简单，学习者容易理解接受import turtle as tt.penup()t.goto(-150,120)t.pendown()t.pensize(3)t.pencolor("blue")t.circle(50)t.penup()t.goto(-40,120)t.pendown()t.pensize(3)t.pencolor("black")t.circle(50)t.penup()t.goto(70,120)t.pendown()t.pensize(3)t.pencolor("red")t.circle(50)t.penup()t.goto(-110,70)t.pendown()t.pensize(3)t.pencolor("yellow")t.circle(50)t.penup()t.goto(0,70)t.pendown()t.pensize(3)t.pencolor("green")t.circle(50)
3、缺点，重复代码，可以用函数循环的方法import tu筠续师诈rtle as tdef yuan(x,y,color): t.penup() t.goto(x,y) t.pendown() t.pensize(3) t.pencolor(color) t.circle(50)yuan(-150,120,"blue")yuan(-40,120,"black")yuan(70,120,"red")yuan(-110,70,"yellow")yuan(0,70,"green")
4、先画一个圆，到复制画一个圆的代码，到画五环，思路简单，学习者容易理解接受，但重复代码太多。使用定义函数，重复执行，精简代码，容易理解，更加明白定义函数的意义。
