The regular expression "split" behaves slightly differently than
string split:
occurrences of pattern", which is not too helpful.
It's the plain str.split() which is unusual in that:
1. it splits on sequences of whitespace instead of one per occurrence;
That can be emulated with the obvious regular expression:
re.compile(r'\W+')
2. it discards leading and trailing sequences of whitespace.
But that can't, or at least I can't figure out how to do it.
[ s in rexp.split(long_s) if s ]
Of course I can discard the blank strings afterward, but
is there some way to do it in the "split" operation? If
not, then the default case for "split()" is too non-standard.
(Also, "if s" won't work; if s != '' might)
