Hi Matthew,

Thanks for such a quick reply.  I know I can get the > by putting it in 
grouping parentheses.  That's not the issue here.  The documentation you quoted 
says that it splits the string by the occurrences _OF_PATTERN_ and that texts 
of all groups are _ALSO_ returned as _PART_ of the resulting list.  It does not 
say anywhere (nor does it even suggest that) that parts of the pattern not 
grouped with parentheses are REMOVED.

That said, I did not report this issue to split hairs (I would rather split 
strings with regular expressions ;)) and perform liguistic analysis of the 
current documentation (which is not set in stone and has been changed before).  
I did that because I spotted an issue which slightly limits usefulness of 
re.split() and suggested a potential improvement which would solve the problem 
and make re.split() even better than it already is.  Whether the powers that be 
do something with this and improve re.split() is of course not my decision.

Cheers,
T
