说明2:返回的regular expression object,提供了match(string), serach(string)等方法,注意与下面将出现的re.match(),re.search()等函数方法区别开来,前者是正则表达式对象的方法,后者是re库的函数方法。但是,两者实现的结果是一样的。 2.re.match(pattern,string,flags=0) 功能:从字符串起始部分对模式进行匹配。...

re.match与re.search的区别 re.match只匹配字符串的开始,如果字符串开始不符合正则表达式,则匹配失败,函数返回None;而re.search匹配整个字符串,直到找到一个匹配。 文件操作 f.seek() 如果要改变文件当前的位置,可以使用f.seek(offset,from_what)函数。 from_what的值,如果是0表示开头,如果是1表示当前位置,2表示...
