How to concisely cascade through multiple regex statements in Python

Question

My dilemma: I\'m passing my function a string that I need to then perform numerous regex manipulations on. The logic is if there\'s a match in the first regex, do one thing

Answer 1

I had the same problem as yours. Here´s my solution:

import re

regexp = {
    'key1': re.compile(r'regexp1'),
    'key2': re.compile(r'regexp2'),
    'key3': re.compile(r'regexp3'),
    # ...
}

def test_all_regexp(string):
    for key, pattern in regexp.items():
        m = pattern.match(string)
        if m:
            # do what you want
            break

It´s a slightly modified solution from the answer of Extracting info from large structured text files
