thanks, I should read the docs but
but more of a basic question following, I was doing the following before:
method = 'split' # came from somewhere else of course
result = re.__dict__[method].(REGEX, TXT)
precompiling the regex
r = compile(REGEX)
does give an regex object which has the needed methods
print dir(r)
['__copy__', '__deepcopy__', 'findall', 'finditer', 'match', 'scanner',
'search', 'split', 'sub', 'subn']
but how do I evaluate them without explicitly calling them?
result = r.__???MAGIC???__[method](TXT)
obviously I am not a Python pro ;)
thanks
chris
