Regular expressions - findall or split? Posted by enquirer (enquirer), 5 April 2006 I want to extract useful information from within a string and discard the remainder in my Python classes - should I use findall, split, or something else?Posted by admin (Graham Ellis), 5 April 2006 Python's findall and split work from opposite "ends" of the problem ... findall returns everything that matches a pattern within a string, whereas split locates all the strings you want to eliminate and returns the remaining parts.In general, if you want to pick out just a few elements (or a small proportion) of the line, findall will do you the best job, but if you want to throw away just a few separators and delimiters, the you'll probably find that split will be the better choice. A similar thing applies to other languages - in Perl, for example, you would be best to use split if you wanted to keep most of the data and throw away separators, but an =~ match is you were looking to cherry pick.
