How to mimic passing a file using python variable

I am trying to figure out how to mimic passing a file to a program and instead of passing the file pass a python variable that has what information the program needs in it.

The syntax I need to mimic:

msfconsole < setofcommands.txt 2>/dev/null

What I would like to do:

answer = os.system('msfconsole < ' + myvariable + ' 2>/dev/null')

I also would be extremely happy if someone knew how to interact with something like msfconsole over a period of time so that when the msfconsole shell is open I could continually get python to type different commands without have to relaunch a new application for each time I wanted to type a series of commands

Thanks a lot in advance.

Instead, of os.system, you should use subprocess:

import subprocess
p=subprocess.Popen(['msfconsole'], stdin=subprocess.PIPE, stderr=subprocess.PIPE)
p.communicate(myvariable)

Note that communicate will block until termination. In general, interactive-like communication with another process just via stdin/stdout is a hard problem, since you must know how the other process delimits ends of messages.

In the case of metasploit, you should use the XMLRPC API instead of the interactive tool msfconsole.
