You're more likely to get help if you provide the minimum code that
demonstrates the problem.

Anyway, your original post said that you're running the child with
os.popen. The documentation says:

"""Open a pipe to or from command. The return value is an open file
object connected to the pipe, which can be read or written depending on
whether mode is 'r' (default) or 'w'."""

In other words, it's one-way.

Are you really using os.popen and not, say, os.popen2?

(Providing actual code would make this clear.)
