1.底盘

在制作蛋糕之前咱们需要先找到一个好看的盘子吖~

def ground_floor(width,height,colors_a,h):
    t.penup()
    t.goto(width, h)
    t.pendown()
    t.begin_fill()
    t.fillcolor(colors_a[0])
    for i in range(360):
        x=draw_x(width, i)
        y=draw_y(height,i)+h
        t.goto(x,y)
    t.end_fill()
    t.begin_fill()
    t.fillcolor(colors_a[1])
    for i in range(180):
        x=draw_x(width, -i)
        y=draw_y(height+10,-i)+h
        t.goto(x,y)
    for i in range(180,360):
        x=draw_x(width, i)
        y=draw_y(height,i)+h
        t.goto(x,y)
    t.end_fill()

2.蛋糕

找到了我们喜欢的盘子后，咱们就可以一层层制作蛋糕啦！

def each_piece(width,height_1,height_2,colors_b,h):
    t.penup()
    t.goto(width,h)
    t.pendown()
    t.begin_fill()
    t.fillcolor(colors_b[0])
    for i in range(360):
        x=draw_x(width, i)
        y=draw_y(height_1,i)+h
        t.goto(x,y)
    t.end_fill()
    t.begin_fill()
    t.fillcolor(colors_b[0])
    for i in range(540):
        x=draw_x(width, i)
        y=draw_y(height_1,i)+height_2+h
        t.goto(x,y)
    t.goto(-width,h)
    t.end_fill()
    t.penup()
    t.goto(width-10,height_2+h)
    t.pendown()
    t.begin_fill()
    t.fillcolor(colors_b[1])
    for i in range(360):
        x=draw_x(width - 10, i)
        y=draw_y(height_1*0.9,i)+height_2+h
        t.goto(x,y)
    t.end_fill()
    t.penup()
    t.goto(width,h)
    t.pendown()
    t.begin_fill()
    t.fillcolor(colors_b[2])
    for i in range(180):
        x=draw_x(width, -i)
        y=draw_y(height_1,-i)+10+h
        t.goto(x,y)
    t.goto(-width,h)
    for i in range(180,360):
        x=draw_x(width, i)
        y=draw_y(height_1,i)+h
        t.goto(x,y)
    t.end_fill()
    t.penup()
    t.goto(width,height_2+h)
    t.pendown()
    t.begin_fill()
    t.fillcolor(colors_b[3])
    for i in range(1800):
        x=draw_x(width, 0.1 * i)
        y=draw_y(-height_1*0.3,i)+h
        t.goto(x,y)
    t.goto(-width,height_2+h)
    for i in range(180,360):
        x=draw_x(width, i)
        y=draw_y(height_1,i)+height_2+h
        t.goto(x,y)
    t.end_fill()

3.祝福

最最最重要滴，一定不要忘记写下对她的祝福吖！

t.write("Happy Birthday!", font=("Curlz MT", 50))
