Is there a way in python to apply a list of regex patterns that are stored in a list to a single string?

Question

i have a list of regex patterns (stored in a list type) that I would like to apply to a string.

Does anyone know a good way to:

1. Apply every regex pattern in the list to the string and
2. Call a different function that is associated with that pattern in the list if it matches.

I would like to do this in python if possible

thanks in advance.

Answer 1

import re

def func1(s):
    print s, "is a nice string"

def func2(s):
    print s, "is a bad string"

funcs = {
    r".*pat1.*": func1,
    r".*pat2.*": func2
}
s = "Some string with both pat1 and pat2"

for pat, func in funcs.items():
    if re.search(pat, s):
        func(s)

The above code will call both functions for the string s because both patterns are matched.
