1、五角星

import turtle as t

a = eval(input("请输入旋转度数："))

def linearmove():
    for i in range(5):
        t.forward(300)
        t.right(144)

t.left(a)
t.color('red', 'red')
t.begin_fill()
linearmove()
t.end_fill()
t.done

2、叠加等边三角形

import turtle as t
t.setup(600, 600, None,None)
t.pu()
t.fd(-120)
t.pensize(5)
t.width(5)

t.pencolor("darkgreen")
t.pd()
t.fd(250)
t.seth(120)

t.pencolor("black")
t.fd(250)
t.seth(-120)

t.pencolor("blue")
t.fd(250)

t.pencolor("purple")
t.fd(250)
t.seth(0)

t.pencolor("green")
t.fd(250)

t.pencolor("gold")
t.fd(250)
t.seth(120)

t.pencolor("yellow")
t.fd(250)
t.seth(-120)

t.pencolor("grey")
t.fd(250)
t.seth(120)

t.pencolor("pink")
t.fd(250)

3、爱心

from turtle import *
def curvemove():
    for i in range(200):
        right(1)
        forward(1)
color('red','pink')
begin_fill()
left(140)
forward(111.65)
curvemove()
left(120)
curvemove()
forward(111.65)
end_fill()
done()

4、螺旋线

import turtle as t

a = input("请输入旋转度数：")
y = eval(a)
def draw_spin():
    colores = ['red', 'purple', 'blue', 'green', 'yellow', 'orange']
    t.bgcolor('black')
    for x in range(200):
        t.pencolor(colores[x % 6])
        t.width(x / 100 + 1)
        t.forward(x)
        t.left(y)

draw_spin()

5、身体质量指数

#计算BMI
weight = float(input("请输入体重(kg)："))
height = float(input("请输入身高(m)："))
bmi = weight/(height*height)
print("您的BMI指数为：{:.2f}".format(bmi))
