I've written a module called scription to help with scripts; it supports giving passwords to programs like ssh.

Here's an example from one of my utility scripts:

-- 8< ---------------------------
#!/usr/local/bin/python

from getpass import getpass
from antipathy import Path
from scription import Command, Execute, Main, OPTION, REQUIRED

...

@Command(
     repo=('repository to pull [default: all]', OPTION),
     path=('base path to search', OPTION, 'p', Path),
     )
def pull(repo, *path):
     '''
     retrieve remote change sets
     '''
     password = getpass('[mercurial] password: ')
     target = repo
     for repo in workhorse(*path):
         if target and repo.filename != target:
             continue
         history = Execute(('hg', 'pull'), cwd=repo, password=password, pty=True)

-- 8< ----------------------------

and in use:

==================================

$ hgc --help
Available commands/options in hgc
    incoming  displays changesets in remote repo not present locally
    list      displays all repos
    log-date  displays all log entries for matching date
    outgoing  displays changesets in remote repo not present locally
    parent    displays parent of active branch
    pull      retrieve remote change sets
    push      send local changesets to remote repo
    status    display status for each repo
    update    update active files to latest version

$ hgc pull
[mercurial] password:

...
===================================

It's available via pip.  Feedback welcome.  :)
