Good question.  I can't count the number of times I've used
line.strip().split() in my own code, just because I didn't 1) read the
documentation closely enough, or 2) try the alternative, but lo and
behold, they are the same, at least in the cases I was trying to account
for.

' a b c '.split() == ' a b c '.strip().split() == 'a b c'.split()

Thanks for pointing this out.

Cheers,
