1、美元人民币转换
getdatas = input("请输入【￥$】数字：")
if getdatas[0] == '$':
n = eval(getdatas[1:])
print("换算是￥{:.2f}".format(n*6))
elif getdatas[0] == '￥':
m = eval(getdatas[1:])
print("换算是${:.2f}".format(m/6))
else:
print("输入有误")
2、变化颜色贪吃蛇
from turtle import *
setup(800,600)
penup()
fd(-300)
pendown()
pensize(25)
speed(10)
color(1,0,0)
fd(40)
seth(-40)
for i in range(4):
color(0,0,i/4)
circle(40,80)
color(i/4,0,0)
circle(-40,80)
circle(40,40)
color(0,i/4,0)
fd(40)
circle(16,180)
fd(40 * 2/3)
3、等边三角形绘制
from turtle import *
setup(800,600)
pensize(10)
speed(10)
color("blue")
fillcolor("yellow")
begin_fill()
fd(100)
for i in range(1,3):
seth(120*i)
fd(100)
end_fill()
hideturtle()
done()
4、叠加等边三角形
from turtle import *
setup(800,600)
pensize(2)
speed(10)
color("blue")
fd(200)
for i in range(1,3):
seth(120*i)
fd(200)
penup()
seth(60) #绝对角度
fd(100)
seth(0)
pendown()
for j in range(1,4):
fd(100)
seth(-120*j)
hideturtle()
done()
5、正方形螺旋线
from turtle import *
setup(800,600)
pensize(2)
speed(10)
color("blue")
for i in range(50):
seth(90*i)
fd(5*i)
hideturtle()
done()
