It is better to use Pexpect module if you want to interact with interactive shells.

But I suggest you to use Python bindings that shipped with gdb.

infothreads.py:

import gdb
gdb.execute('info threads')
gdb.execute('continue')

Run it using -x option of gdb:

gdb -x infothreads.py -p 21686

Documentation on Python bindings may be found here: Python API
