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.
