正则表达式通常缩写成“regex”,单数有regexp、regex,复数有regexps、regexes、regexen。 通常情况下,如果一个文本中出现了多个匹配,正则表达式返回第一个匹配,如果将 global 设置为 true,则会返回全部匹配;匹配模式是大小写敏感的,如果设置了 ignore case 为 true,则将忽略大小写区别。 有时侯正则表达式也简称为表...

In addition, the regular expression functions in the re module also work on binary sequences, if the regex is compiled from a binary sequence instead of a str. The % operator does not work with binary sequences in Python 3.0 to 3.4, but should be supported in version 3.5 according to ...
