Match a line with multiple regex using Python

 https://stackoverflow.com/questions/8888567/match-a-line-with-multiple-regex-using-python

You can use the built in functions any (or all if all regexes have to match) and a Generator expression to cycle through all the regex objects.

any (regex.match(line) for regex in [regex1, regex2, regex3])

(or any(re.match(regex_str, line) for regex in [regex_str1, regex_str2, regex_str2]) if the regexes are not pre-compiled regex objects, of course)

However, that will be inefficient compared to combining your regexes in a single expression. If this code is time- or CPU-critical, you should try instead to compose a single regular expression that encompasses all your needs, using the special | regex operator to separate the original expressions.

A simple way to combine all the regexes is to use the string join method:

re.match("|".join([regex_str1, regex_str2, regex_str2]), line)

A warning about combining the regexes in this way: It can result in wrong expressions if the original ones already do make use of the | operator.
