Question

How do I split up a string into several parts of a number of words in python. For example, turn a 10,000 word string into ten 1,000 word strings. Thanks.

Answer 1

def splitter(n, s):
    pieces = s.split()
    return (" ".join(pieces[i:i+n]) for i in range(0, len(pieces), n))

for piece in splitter(1000, really_long_string):
    print(piece)

Where n is number of words; s is the long string.
This will yield ten 1000 word strings from a 10000 word string like you ask.
Note that you can also use iterools grouper recipe but that would involve making 1000 copies of the iterator for your string: expensive I think.

Also note that this will replace all whitespace with spaces. If this isn’t acceptable, you’ll need to try something else.
