1、用循环画五角星

import turtle
for i in range(5):
    turtle.forward(200)
    turtle.right(144)

　　

2、用循环画同心圆

import turtle
for i in range(6):
    turtle.up()
    turtle.goto(0,-25*i)
    turtle.down()
    turtle.circle(25*i)

3、用while循环画太阳花

 

from turtle import *
color(\'pink\')
begin_fill()
while True:
    forward(200)
    left(170)
    if abs(pos())<1:
        break
end_fill()
done()

4、用函数定义画五个五角星

import turtle
turtle.begin_fill()
turtle.up()
turtle.goto(-600,220) 
turtle.down()
for i in range(5):
    turtle.forward(150)
    turtle.right(144)
turtle.end_fill()

turtle.begin_fill()
turtle.up()
turtle.goto(-400,295)
turtle.setheading(305)
turtle.down()    
for i in range(5):
    turtle.forward(50)
    turtle.right(144)
turtle.end_fill()

turtle.begin_fill()
turtle.up()
turtle.goto(-350,212)
turtle.setheading(30)
turtle.down()
for i in range(5):
    turtle.forward(50)
    turtle.right(144)
turtle.end_fill()

turtle.begin_fill()
turtle.up()
turtle.goto(-350,145)
turtle.setheading(5)
turtle.down()
for i in range(5):
    turtle.forward(50)
    turtle.right(144)
turtle.end_fill()

turtle.begin_fill()
turtle.up()
turtle.goto(-400,90)
turtle.setheading(300)
turtle.down()
for i in range(5):
    turtle.forward(50)
    turtle.right(144)
turtle.end_fill()

5、用函数定义画钻石花瓣的太阳花

import turtle
turtle.speed(30)
turtle.color("yellow")
turtle.fillcolor("pink")
def draw_rhombus(size):
    for i in range(2):
        turtle.fd(size)
        turtle.left(20)
        turtle.fd(size)
        turtle.left(160)
turtle.right(90)
turtle.begin_fill()
for i in range(36):
    draw_rhombus(100)
    turtle.left(10)
turtle.end_fill()
turtle.fd(400)

6、输入学号，识别年级、专业、序号

s= input("请输入学号：")
print("您的年级：{}级".format(s[0:4]))
if(int(s[8:10])==43):
    print("专业名称：网络工程专业（一班）")
elif(int(s[8:10])==44):
    print("专业名称：网络工程专业（二班）")
print("班号为：{}".format(s[-2:]))

7、输入1-7的数字，输出对应的“星期几”

day="星期一星期二星期三星期四星期五星期六星期日"
a=eval(input("请输入星期数字（1-7）:"))

pos=(a-1)*3

print(day[pos:pos+3])

8、识别身份证号中的省市区、年龄、性别

import time
 
provinces = {
    11:\'北京市\',
    12:\'天津市\',
    13:\'河北省\',
    14:\'山西省\',
    15:\'内蒙古自治区\',
    21:\'辽宁省\',
    22:\'吉林省\',
    23:\'黑龙江省\',
    31:\'上海市\',
    32:\'江苏省\',
    33:\'浙江省\',
    34:\'安徽省\',
    35:\'福建省\',
    36:\'江西省\',
    37:\'山东省\',
    41:\'河南省\',
    42:\'湖北省\',
    43:\'湖南省\',
    44:\'广东省\',
    45:\'广西壮族自治区\',
    46:\'海南省\',
    50:\'重庆市\',
    51:\'四川省\',
    52:\'贵州省\',
    53:\'云南省\',
    54:\'西藏自治区\',
    61:\'陕西省\',
    62:\'甘肃省\',
    63:\'青海省\',
    64:\'宁夏回族自治区\',
    65:\'新疆维吾尔自治区\',
    71:\'台湾省\',
    81:\'香港特别行政区\',
    91:\'澳门特别行政区\'
}
 
def check(ID):
    province=ID[0:2]
    birthdayYear=ID[6:10]
    localYear=time.strftime(\'%Y\')
    age=int(localYear)-int(birthdayYear)
    sex=ID[16:17]
    print("省份为：", provinces.get(int(province)))
    print("年龄为：{}".format(age))
    if int(sex)%2==0:
        print("性别：女")
    else:
        print("性别:男")
ID=input("请输入身份证号：")
check(ID)

9、用字符串操作生成python文档各库的网址

a="https://docs.python.org/3.6/library/index"
b=".html"
address=a+b
print(address)
