Python之路，day6-Python基础
1.config 模块
1 import configparser 2 3 conf = configparser.ConfigParser() 4 conf["DEFAULT"] = {'ServerAliveInterval': '45', 5 'Compression': 'yes', 6 'CompressionLevel': '9'} 7 conf['wwwwwwwww'] = {} 8 conf['wwwwwwwww']['user'] = 'baidu' 9 conf['topsecret.server.com'] = {} 10 topsecret = conf['topsecret.server.com'] 11 topsecret['Host Port'] = '50022' 12 with open('conf.ini','w') as f: 13 f.write(conf)
2.hashlib操作
1 import hmac 2 h = hmac.new(b'hsc') 3 h.update(b'12233') 4 print(h)
3.random模块
1 import random 2 print(random.random()) 3 print(random.randint(1,2)) #0,1,2 随机 4 print(random.randrange(1,2))#0,1 随机 5 6 checkcode = '' 7 for i in range(6): 8 current = random.randrange(0,6) 9 if current != i: 10 temp = chr(random.randint(65,90)) 11 else: 12 temp = random.randint(0,9) 13 checkcode += str(temp) 14 print(checkcode)
4.shelve模块
1 import shelve 2 3 d = shelve.open('shelve_test') 4 5 def stu_data(name,age): 6 print("register stu",name,age) 7 name = ["hsc","***","abm"] 8 info = {"name":"hsc","age":18} 9 10 d["test"] = name 11 d["info"] = info 12 d['func'] = stu_data
5.shutil模块
1 import shutil 2 3 # f1 = open("random mod .py") 4 # f2 = open("random_new .py",'w') 5 # shutil.copyfileobj(f1,f2) 6 7 # shutil.copyfile("笔记",r'd:\123') 8 shutil.make_archive('www','gztar',root_dir=r'C:\Users\heshaochuan\PycharmProjects\py_s15\day6')
6. logging模块
1 import logging 2 3 log_test = logging.getLogger('TEST') 4 logging.basicConfig(filename='wwwwwwwwww.log',level=logging.INFO) 5 logging.debug('mthgh') 6 logging.info('2131234324')
7.re模块

'.' 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'} |
