You made a common mistake of using a loop index instead of iterating
directly.
Instead of:
  for i in xrange(len(c)):
     cp.extend(c[i].split(j))

Just write:
  for words in c:
     cp.extend(words.split(j))

Then you won't make a bounds mistake, and this snippet becomes a LOT
more readable.

(Of course, you're better using re.split instead here, but the
principle is good).
