‘.‘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‘}
