You should learn about re.VERBOSE: http://docs.python.org/lib/node46.html#l2h-414 With this flag, your commented version could be the actual regex, instead of repeating it in code with the whitespace and comments removed: matchstr = re.compile(r''' (\(\d+,\d+\)) # (0018,0014) \s # [space] (..*) # Contrast/Bolus Administration Route Sequence \s # space ([a-z]{2}) # SQ - two letters and no more \s # [space] (\d) # 1 - single digit re.I) # case insensitive ''', re.I|re.VERBOSE) Kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
