Hi,

I have had some success in controlling GDB (via MI) from python, using
the subprocess module and communicating with GDB via pipes.
(http://docs.python.org/library/subprocess.html)

The main issue so far is that some applications detect when they are
running with pipes instead of a terminal for output, and buffer program
output by block rather than line as on a terminal, leading to delays in
receiving program output issued via printf, for example, unless it is
followed by an explicit fflush call.

(I too would be interested in an example of using pexpect to control GDB)
