1.字符串操作:

  • 解析身份证号:生日、性别、出生地等。
id = input("请输入身份证号码:")
shengfen = id[0:2]
nian = id[6:10]
yue = id[10:12]
ri = id[12:14]
diqu={'北京': 11, '上海': 31, '湖北': 42, '云南': 53,
      '天津': 12, '江苏': 32, '湖南': 43, '西藏': 54,
      '河北': 13, '浙江': 33, '广东': 44, '陕西': 61,
      '山西': 14, '安徽': 34, '广西': 45, '甘肃': 62,
      '内蒙': 15, '福建': 35, '海南': 46, '青海': 63,
      '辽宁': 21, '江西': 36, '重庆': 50, '宁夏': 64,
      '吉林': 22, '山东': 37, '四川': 51, '新疆': 65,
      '黑龙江': 23, '河南': 41, '贵州': 52, '新疆兵团': 66,
      '台湾': 71, '香港': 81, '澳门': 91}
for key in diqu:
    if shengfen == str(diqu[key]):
        shengfen = key
print("解析如下:")
print('籍贯:'+shengfen)
print("出生日期:"+nian+""+yue+""+ri+"")
if (int(id[-2]) % 2) == 0:
    print("性别:女性")
else:
    print("性别:男性")

 

  • 凯撒密码编码与解码

  加密:

from idna import unichr

def Du():
    XinXi = open(r"..\bd\venv\Password\monkey.txt", 'r', encoding='utf8')
    JiaMi = XinXi.read()
    XinXi.close()
    return JiaMi

def Xie():
    XinXi = open(r"..\bd\venv\Password\monkey.txt", 'w', encoding='utf8')
    XinXi.write(JiaMi)
    XinXi.close()

JiaMi = Du()

def JM(b):

    c = ''
    for i in b:
        c += unichr(ord(i) + 3)
        # print(unichr(ord(i)+3))
    b = c
    return b
print("加密前:"+JiaMi)

JiaMi = JM(JiaMi)

print("加密后:"+JiaMi)

Xie()

  解密:

from idna import unichr

XinXi = open(r"..\bd\venv\Password\monkey.txt",'r+',encoding='utf8')
JieMi = XinXi.read()
c=''
for i in JieMi:
c+=unichr(ord(i)-3)
#print(unichr(ord(i)+3))
print("解密前:"+JieMi)
JieMi=c
XinXi.seek(0)
XinXi.truncate()
print("解密后:"+JieMi)
XinXi.write(JieMi)
XinXi.close()

 

  • 网址观察与批量生成
for i in range(1,16):
  print('http://news.gzcc.cn/html/xiaoyuanxinwen/{}.html'.format(i))

2.英文词频统计预处理

  • 下载一首英文的歌词或文章或小说。
  • 将所有大写转换为小写
  • 将所有其他做分隔符(,.?!)替换为空格
  • 分隔出一个一个的单词
  • 并统计单词出现的次数。
XinXi = open(r"..\bd\venv\GeCi\geci.txt",'r+',encoding='utf8')
GeCi= XinXi.read()
XinXi.close()

GeCi_ist = GeCi.replace('\n', ' ').replace(',', ' ').replace('(', ' ').replace(')', ' ').lower().split(' ')
ZiDian = { }
for str in GeCi_ist:
    if str in ZiDian.keys():
        ZiDian[str] = ZiDian[str] + 1
    else:
        ZiDian[str] = 1

del ZiDian['']
print(sorted(ZiDian.items(),key=lambda x:x[1],reverse=True))

 

3.文件操作

  • 同一目录、绝对路径、相对路径
open(r"..\bd\venv\GeCi\geci.txt",'r+',encoding='utf8')
  • 凯撒密码:从文件读入密函,进行加密或解密,保存到文件。
from idna import unichr

XinXi = open(r"..\bd\venv\Password\monkey.txt",'r+',encoding='utf8')
JieMi = XinXi.read()
c=''
for i in JieMi:
    c+=unichr(ord(i)-3)
    #print(unichr(ord(i)+3))
print("解密前:"+JieMi)
JieMi=c
XinXi.seek(0)
XinXi.truncate()
print("解密后:"+JieMi)
XinXi.write(JieMi)
XinXi.close()

 

  • 词频统计:下载一首英文的歌词或文章或小说,保存为utf8文件。从文件读入文本进行处理。
XinXi = open(r"..\bd\venv\GeCi\geci.txt",'r+',encoding='utf8')
GeCi= XinXi.read()
XinXi.close()

GeCi_ist = GeCi.replace('\n', ' ').replace(',', ' ').replace('(', ' ').replace(')', ' ').lower().split(' ')
ZiDian = { }
for str in GeCi_ist:
    if str in ZiDian.keys():
        ZiDian[str] = ZiDian[str] + 1
    else:
        ZiDian[str] = 1
del ZiDian['']
print(sorted(ZiDian.items(),key=lambda x:x[1],reverse=True))

 

 4.函数定义

  • 加密函数
def JiaM(b):

    c = ''
    for i in b:
        c += unichr(ord(i) + 3)
        # print(unichr(ord(i)+3))
    b = c
    return b

 

  • 解密函数
def JieM(b):

    c = ''
    for i in b:
        c += unichr(ord(i) - 3)
        # print(unichr(ord(i)-3))
    b = c
    return b

 

  • 读文本函数
def Du():
    XinXi = open(r"..\bd\venv\Password\monkey.txt", 'r', encoding='utf8')
    JiaMi = XinXi.read()
    XinXi.close()
    return JiaMi
