How to use the zulip.integrations.perforce.git_p4.View function in zulip

specList = p4CmdList("client -o")
    if len(specList) != 1:
        die('Output from "client -o" is %d lines, expecting 1' %
            len(specList))

    # dictionary of all client parameters
    entry = specList[0]

    # the //client/ name
    client_name = entry["Client"]

    # just the keys that start with "View"
    view_keys = [ k for k in entry.keys() if k.startswith("View") ]

    # hold this new View
    view = View(client_name)

    # append the lines, in order, to the view
    for view_num in range(len(view_keys)):
        k = "View%d" % view_num
        if k not in view_keys:
            die("Expected view key %s missing" % k)
        view.append(entry[k])

    return view
