    access variables from one Python session to another on the samemachine?

    Suppose I have two different command windows going on the same
    machine, each running their own Python interpreters.

    Is it possible to access the variables in one of the interpreter-
    sessions from the other?

    It turns out I have limited control over one of the sessions (i.e.
    cannot control all the code that is run from there), but complete
    control over the other.

    I get the feeling this has been asked before, but I'm not sure how to
    pose the question in such a way that it would show up on a search.
    It's confusing.

    Thanks.

      IMHO without "significan t" access to both programs I believe the answer is no.
      You would have to introduce something in the master window that would "expose"
      data to the slave window. Normally this is done via: socket server, pipes,
      shared database, etc.

      Does the master, provide output that could be captured and used as input to the
      slave? If so, you might be able to use subprocess module to make it work.

          Depending on what 'limited control' means, the simplest choice would
          be writing stuff to a plain text file from the master and reading it
          from the slave. This may or may not work depending on your environment
          though.

          Cheers,
          Daniel

              This disk-writing approach seems to be simplest & less intrusive.
              Thanks! I'll try it.
