1.字符串操作

　　解析身份证号：生日、性别、出生地等

# -*- coding:utf-8 -*-
idCard=input("输入身份证号码：")
local=idCard[0:2]
year= idCard[6:10]
month= idCard[10:12]
day= idCard[12:14]
sex=idCard[16:17]
address={'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','82':'澳门特别行政区'}
print("地区：" + address.get(local),"生日：{}年{}月{}日".format(year, month, day))
if(int(sex)%2==0):
    print("性别：女")
else:
    print("性别：男")

　　凯撒密码编码与解码

def decode():
    code = input("请输入原码:\n")
    decode = ""
    for n in code:
        if -128 >= ord(n) or 127 <= ord(n):
            print("原码取值超出范围！！！")
            break
        decode += chr(ord(n) + 3)

    print("原码：" + code + "\n")
    print("编码：" + decode + "\n")
    return


def encode():
    decode = input("请输入编码:\n")
    encode = ""
    for n in decode:
        if -125 >= ord(n) or 130 <= ord(n):
            print("编码取值超出范围！！！")
            break
        encode += chr(ord(n) - 3)

    print("编码：" + decode + "\n")
    print("译码：" + encode + "\n")
    return


while 1:
    choose = input("请选择功能:\n 1、编码\n 2、译码\n")
    if choose == "1":
        decode()
    elif choose == "2":
        encode()
    else:
        print("\n\n请重新输入：\n\n")

2.英文词频统计

import re

file = open("two tigers.txt", "r+")
str = file.read()
print("读取的字符串是 : \n", str)

str = re.sub('[\r\n\t,]', ' ', str)
words = str.split(" ")

single = []

for word in words:
    if (word not in single):
        single.append(word)

i = 1
while single:
    print(single[0], "出现次数：", words.count(single[0]), end="     ")
    single.pop(0)

    if i % 4 == 0:
        print("\n")

    i += 1

file.close()
