Presumably you want to join the list back into a string, with something
like:

	' '.join(remove)

or in general

	S.join(L)

where S is a delimiter string and L is a sequence.  Note that this may
have an surprising effect since L.split() with no argument will split on
_any_ block of whitespace, whereas ' '.join(L) will only join the parts
back with a single space:

>>> L = 'this has  a   lot    of    spaces'.split()
>>> ' '.join(L)
'this has a lot of spaces'

This may not bother you, but I thought I'd point it out as a clear
difference.
