[Python] popen3 child_stdin

popen3(cmd[, mode[, bufsize]]) Executes cmd as a sub-process. Returns the
file objects (child_stdin, child_stdout, child_stderr). Availability: Unix,
Windows. New in version 2.0.

I may be having a moment of brain fade, but I can't see how I get hold of
child_stdin etc, having started up a DOS program with popen3

Help?

Peter Hansen: If you mean you don't understand what the docs are telling you, then this example based on the above text might help: childStdin, childStdout, childStderr = popen3(cmd, mode, bufsize) The return value is expressed as a tuple of three elements.... -Peter
Ddoc: It was brainfade. The function returns a tuple, of course. It works, and solves one Linux task I had been contemplating for a while, but doesn't of itself accomplish a job I want to do in Windows I should be able to automate a DOS program - or rather seize its interface and control what goes in as from a keyboard, and catch what comes out as if to the screen, thus programattically determining what gets typed to it and what gets shown to a notional user, but I suspect I need to use pipes rather
