python-valve

python-valve is a Python library which intends to provide an all-in-one interface to various Valve products and services, including:

• Steam web API
• Local Steam Clients
• Source servers
  • A2S server queries
  • RCON
• Source master server
• Valve Data Format (.vdf) (de)serialiser

RCON Example

In this example we connect to a Source servers remote console and issue a simple echo command to it.

from valve.source.rcon import RCON

SERVER_ADDRESS = ("...", 27015)
PASSWORD = "top_secret"

with RCON(SERVER_ADDRESS, PASSWORD) as rcon:
    print(rcon("echo Hello, world!"))

Server Query Example

In this example we demonstrate the Source master server and A2S query implementations by listing all Team Fortress 2 servers in Europe and Asia running the map ctf_2fort along with the players on each server sorted by their score.

import valve.source.a2s
import valve.source.master_server

msq = valve.source.master_server.MasterServerQuerier()
try:
    for address in msq.find(region=[u"eu", u"as"],
                            gamedir=u"tf",
                            map=u"ctf_2fort"):
        server = valve.source.a2s.ServerQuerier(address)
        info = server.info()
        players = server.players()

        print "{player_count}/{max_players} {server_name}".format(**info)
        for player in sorted(players["players"],
                             key=lambda p: p["score"], reverse=True):
            print "{score} {name}".format(**player)
except valve.source.a2s.NoResponseError:
    print "Master server request timed out!"

Testing

python-valve uses py.test for running its test suite as well as using Jenkins CI to actively test the A2S implementation against thousands of servers. See http://servers.tf:8080/.

Python 3

Currently there is partial support for Python 3 -- 3.4 to be specific. Everything in valve.source will/should work in both Python 2.7 and Python 3.4 but currently that is the only section that has been ported. The rest will be updated in due course but those other components need reworking anyway.
