http://python.org/doc/current/lib/os-newstreams.html#l2h-1379 says: popen2( cmd[, mode[, bufsize]]) Executes cmd as a sub-process. Returns the file objects (child_stdin, child_stdout). But for me it actually returns (child-output, child-input). Or... is it a semantci issue? that is child_stdin - is "the input _from_ child?" Anyway - it is confusing.

Logged In: YES user_id=1057404 The above is not-a-bug, but this documentation patch below might serve to remove any confusion. ### --- libos.tex- Sat Jun 5 17:28:52 2004 +++ libos.tex Sat Jun 5 17:32:40 2004 @@ -384,6 +384,10 @@ \versionadded{2.0} \end{funcdesc} +It should be noted that \code{\var{child_stdin}, \var{child_stdout}, and +\var{child_stderr}} are named from the child process' point of view, i.e. the +stdin of the child. + This functionality is also available in the \refmodule{popen2} module using functions of the same names, but the return values of those functions have a different order. ###
