use default argument binding:

         def replace(match, replacement_dict=replacement_dict):
             key = match.group(1)
             if replacement_dict.has_key(key):
                 return replacement_dict[key]
             else:
                 return ''

or:

         def replace(match, get=replacement_dict.get):
             return get(match.group(1), '')
