Or possibly the more pythonish:

elif os.path.exists('.hg_archival.txt'):
    hgarchival = open('.hg_archival.txt')
    kw = dict()
    for line in hgarchival:
        l = line.split(':', 1)
        kw[l[0]] = l[1].strip()
    if kw.get('tag'):
        version =  kw.get('tag')
    elif kw.get('latesttag') and kw.get('latesttagdistance', '0') != '0':
        version = '%(latesttag)s+%(latesttagdistance)s-%(node).12s' % kw
    else:
        version = kw.get('node', '')[:12]
