the python 2.3.3 library documentation for popen2 says:
( file:///usr/share/doc/python2.3/html/lib/module-popen2.html)

popen2( cmd[, bufsize[, mode]])
Executes cmd as a sub-process. Returns the file objects  (child_stdout, child_stdin).

however, the actual behavior of python 2.3.3 is to return (child_stdin, child_stdout) - in the reverse order.

I haven't checked with popen3 and popen4.

thanks.

This has either been fixed in Python 2.4, or you're
confusing popen2.popen2 with os.popen2, which does return
the file objects in the order you describe.
