这些函数使用 RE 字符串作为第一个参数,而後面的参数则与相应 `RegexObject` 的方法参数相同,返回则要么是 None 要么就是一个 `MatchObject` 的实例。 #!python >>> print re.match(r'From"s+', 'Fromage amk') None >>> re.match(r'From"s+', 'From amk Thu May 14 19:12:10 1998') <re.M...
re.match 尝试从字符串的起始位置匹配一个模式,如果不是起始位置匹配成功的话,match() 就返回 none。 规则是 re.match(pattern,string,flag) 举例说明: importreprint(re.match('www','www.baidu.com'))print(re.match('www','www.baidu.com').span())print(re.match('www','ewwww'))#输出<re.Match...

re.compile(pattern,flags=0) Compile a regular expression pattern into aregular expression object, which can be used for matching using its match(),search()and other methods. 功能:对正则表达式进行预编译。 说明1:使用预编译的代码对象,比直接使用字符串要快,因为解释器在执行字符串形式的代码前都必须把...
