Limit Lines of Output using python

Question

I've got a simple script that counts the number of words in a data set (it's more complicated than that, but that's one of the functions), but there are so many words that the output is too much to see in the command prompt window. What I'd like to be able to do is incorporate the "More..." feature that help libraries have, but I have no idea how to do it. I also don't know if I'm asking the question correctly because a Google search yielding nothing.

I'm running Windows.

Answer 1

If you are using linux, you should look up the comand less. It allows you to page thru a test file. You can either write your list to a file or pipe it into less (havent tried that myself)

Answer 2

Supposedly, Windows has "more"
[http://superuser.com/questions/426226/less-or-more-in-windows],

For Linux+less; this works:

from subprocess import Popen, PIPE
less = Popen("less", stdin=PIPE)
less.stdin.write(b"n".join("This is line number
{}".format(i).encode("UTF-8") for i in range(1000)))
less.wait()
