I wrote the below code

    profile = get_container_profile(copy.deepcopy(profile))
    kw_overrides = copy.deepcopy(kwargs)
    def select(key, default=None):
        kw_overrides_match = kw_overrides.pop(key, None)
        profile_match = profile.pop(key, default)
        if (kw_overrides_match is None):
            return profile_match
        return kw_overrides_match
    path = select('path')
    if exists(name, path=path):
        raise CommandExecutionError("Container    '{0}'    already    exists".format(name))
    _ensure_exists(orig, path=path)
    if (state(orig, path=path) != 'stopped'):
        raise CommandExecutionError("Container    '{0}'    must    be    stopped    to    be    cloned".format(orig))
    backing = select('backing')
    snapshot = select('snapshot')
    if (backing in ('dir',)):
        snapshot = False
    if (not snapshot):
        snapshot = ''
    else:
        snapshot = '-s'
    size = select('size', '1G')
    if (backing in ('dir', 'overlayfs', 'btrfs')):
        size = None
    if (version() >= _LooseVersion('2.0')):
        cmd = 'lxc-copy'
        cmd += '    {0}    -n    {1}    -N    {2}'.format(snapshot, orig, name)
    else:
        cmd = 'lxc-clone'
        cmd += '    {0}    -o    {1}    -n    {2}'.format(snapshot, orig, name)
    if path:
        cmd += '    -P    {0}'.format(pipes.quote(path))
        if (not os.path.exists(path)):
            os.makedirs(path)
    if backing:
        backing = backing.lower()
        cmd += '    -B    {0}'.format(backing)
        if (backing not in ('dir', 'overlayfs')):
            if size:
                cmd += '    -L    {0}'.format(size)
    ret = __salt__['cmd.run_all'](cmd, python_shell=False)
    return _after_ignition_network_profile(cmd, ret, name, network_profile, path, nic_opts)

What's a good function header?
