steam-client 4.0.0

Steam client library for Python

Steam Client

A Python library for interacting with a locally installed Steam client — enumerate your game library/non-steam games, read game metadata and artwork paths, send Steam URI commands, and query the Steam Web API.

---

Installation

Requires Python 3.8+.

pip install steam-client

Or install from source:

pip install -e .

---

Quickstart

from steam_client.steam import Steam

steam = Steam()  # Uses default path: C:\Program Files (x86)\Steam

# On Windows, auto-detect path from registry:
from steam_client.utils import steam_from_registry
steam = steam_from_registry()

---

Common Operations

List all installed games

for game in steam.library.games():
    print(game.appid, game.name)

Find a game

game = steam.library.game_by_id("440")       # by app ID
game = steam.library.game_by_name("Portal 2") # by name (case-insensitive)

Artwork paths

game.header   # Path to header image    (460×215 jpg)
game.grid     # Path to grid image      (600×900 jpg)
game.hero     # Path to hero image
game.icon     # Path to icon file, or None

Launch and manage games via Steam URI commands

from steam_client.commands import Commands, SteamWindows

commands = Commands()
commands.run_game_id("440")         # Launch a game
commands.store("440")               # Open store page
commands.install("440")             # Prompt install
commands.uninstall("440")           # Prompt uninstall
commands.open(SteamWindows.FRIENDS) # Open a Steam window
commands.open_url("https://store.steampowered.com")

Or launch a game directly from a SteamGame object:

game.run()

Users and shortcuts

for user in steam.users:
    print(user.user.data.PersonaName)

for shortcut in steam.library.shortcuts():
    print(shortcut.appname)

Steam Web API

from steam_client.web_api import WebAPI

api = WebAPI()
apps = api.get_app_list()

---

Platform Notes

Platform	Default path	Registry helper
Windows	C:\Program Files (x86)\Steam	steam_from_registry()
Linux	~/.local/share/steam	Not available

Pass a custom path to override the default:

steam = Steam("/custom/steam/path")

Requires read access to local Steam config files (libraryfolders.vdf, shortcuts.vdf, appmanifest files).
