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.  :)
