It's almost the Dragon Boat Festival, I will draw a plate of rice dumplings with Python for you

The Dragon Boat Festival is approaching. I will use Python to draw a plate of rice dumplings for everyone. The Python library used is still the familiar turtle. I wish everyone a healthy Dragon Boat Festival in advance.

First, let's draw a plate. The code is implemented as follows:

 minAngle = (2 * math.pi / 360) * angle / steps
rotateAngle = rotateAngle / 360 * 2 * math.pi
penup() # 起笔
setpos(b * math.sin(rotateAngle), -b * math.cos(rotateAngle))
pendown() # 落笔
for i in range(steps):
    nextPoint = [a * math.sin((i + 1) * minAngle), -b * math.cos((i + 1) * minAngle)]
    nextPoint = [nextPoint[0] * math.cos(rotateAngle) - nextPoint[1] * math.sin(rotateAngle),
                 nextPoint[0] * math.sin(rotateAngle) + nextPoint[1] * math.cos(rotateAngle)]
    setpos(nextPoint)

Take a look at the effect:

Next, let's draw rice dumplings again. The code is implemented as follows:

 pensize(2) # 画笔宽度
pencolor(2, 51, 12) # 画笔颜色
fillcolor(4, 77, 19) # 填充色
begin_fill()
fd(200) # 向前
circle(15, 120) #画圆弧
fd(200)
circle(15, 120)
fd(200)
circle(15, 120)
fd(200)
circle(15, 60)
fd(100)
circle(15, 90)
fd(173)
circle(1, 90)
end_fill()
penup()
fd(100)
right(60)
back(105)
a = pos()
pendown()
color(60, 67, 0)
fillcolor(85, 97, 9)
begin_fill()
fd(120)
goto(a)
penup()
back(15)
left(90)
fd(20)
right(90)
pendown()
fd(150)
right(120)
fd(24)
right(60)
fd(120)
right(60)
fd(24)
end_fill()
begin_fill()
left(110)
fd(65)
left(100)
fd(24)
left(80)
fd(50)
end_fill()

Take a look at the effect:

It feels too little to put one zongzi on one plate, so let's add two more and see the effect:

Finally, let's add some text, and the code is implemented as follows:

 write("祝大家端午安康", move=False, align="center", font=("Comic Sans", 18, "bold"))

Take a look at the final effect:
