Python之路，day6-Python基础

1.config 模块

 import configparser

 conf = configparser.ConfigParser()
 conf["DEFAULT"] = {'ServerAliveInterval': '',
                       'Compression': 'yes',
                      'CompressionLevel': ''}
 conf['wwwwwwwww'] = {}
 conf['wwwwwwwww']['user'] = 'baidu'
 conf['topsecret.server.com'] = {}
 topsecret = conf['topsecret.server.com']
 topsecret['Host Port'] = ''
 with open('conf.ini','w') as f:
     f.write(conf)

2.hashlib操作

 import hmac
 h = hmac.new(b'hsc')
 h.update(b'')
 print(h)

3.random模块

 import random
 print(random.random())
 print(random.randint(1,2)) #0,1,2  随机
 print(random.randrange(1,2))#0,1   随机

 checkcode = ''
 for i in range(6):
     current = random.randrange(0,6)
     if current != i:
         temp = chr(random.randint(65,90))
     else:
         temp = random.randint(0,9)
     checkcode += str(temp)
 print(checkcode)

4.shelve模块

 import shelve

 d = shelve.open('shelve_test')

 def stu_data(name,age):
     print("register stu",name,age)
 name = ["hsc","xjp","abm"]
 info = {"name":"hsc","age":18}

 d["test"] = name
 d["info"] = info
 d['func'] = stu_data

5.shutil模块

 import shutil

 # f1 = open("random mod .py")
 # f2 = open("random_new .py",'w')
 # shutil.copyfileobj(f1,f2)

 # shutil.copyfile("笔记",r'd:\123')
 shutil.make_archive('www','gztar',root_dir=r'C:\Users\heshaochuan\PycharmProjects\py_s15\day6')

6. logging模块

 import logging

 log_test = logging.getLogger('TEST')
 logging.basicConfig(filename='wwwwwwwwww.log',level=logging.INFO)
 logging.debug('mthgh')
 logging.info('')

7.re模块

常用正则表达式符号

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

'.'     默认匹配除\n之外的任意一个字符，若指定flag DOTALL,则匹配任意字符，包括换行 '^'     匹配字符开头，若指定flags MULTILINE,这种也可以匹配上(r"^a","\nabc\neee",flags=re.MULTILINE) '$'     匹配字符结尾，或e.search("foo$","bfoo\nsdfsf",flags=re.MULTILINE).group()也可以 '*'     匹配*号前的字符0次或多次，re.findall("ab*","cabb3abcbbac")  结果为['abb', 'ab', 'a'] '+'     匹配前一个字符1次或多次，re.findall("ab+","ab+cd+abb+bba") 结果['ab', 'abb'] '?'     匹配前一个字符1次或0次 '{m}'   匹配前一个字符m次 '{n,m}' 匹配前一个字符n到m次，re.findall("ab{1,3}","abb abc abbcbbb") 结果'abb', 'ab', 'abb'] '|'     匹配|左或|右的字符，re.search("abc|ABC","ABCBabcCD").group() 结果'ABC' '(...)' 分组匹配，re.search("(abc){2}a(123|456)c", "abcabca456c").group() 结果 abcabca456c     '\A'    只从字符开头匹配，re.search("\Aabc","alexabc") 是匹配不到的 '\Z'    匹配字符结尾，同$ '\d'    匹配数字0-9 '\D'    匹配非数字 '\w'    匹配[A-Za-z0-9] '\W'    匹配非[A-Za-z0-9] 's'     匹配空白字符、\t、\n、\r , re.search("\s+","ab\tc1\n3").group() 结果 '\t'   '(?P<name>...)' 分组匹配 re.search("(?P<province>[0-9]{4})(?P<city>[0-9]{2})(?P<birthday>[0-9]{4})","371481199306143242").groupdict("city") 结果{'province': '3714', 'city': '81', 'birthday': '1993'}
