#Console for evrything ;)

def try_to_get_steam_path():
    #geht alle möglichen laufwerke durch um den steam path zu finden
    laufwerke = ["C:", "D:", "E:", "F:"]
    try:
        for lauf in laufwerke:
            try:
                val = os.listdir(lauf)

                    print("steam found in Disk:", lauf)
                    path = lauf + "\SteamLibrary" + "\steamapps" + "\common"
                    print("Path:", path)

#funktioniert also das die eine funktion den steam path bekommt und ihn dann erfolgreich der anderen funktion übermittelt

            break
            pass
        elif com == "deb":
            steam_path = try_to_get_steam_path()
            print()
            print(steam_path)
            #steam_games_info(steam_path)
        elif com == "deb2":
            enter_steam_game()
        else:
            print("Error")
main()

Idle output

[WinError 3] Das System kann den angegebenen Pfad nicht finden: D:\\SteamLibrary\\steamapps\\common\\

What exactly your problem and why do you do think that there is a bug in the os module? Please provide more details.

I don't know which branch of the if is raising the exception, but IIRC os.listdir raises OSError if the path cannot be found (which appears to be the case).

Your script appears to list the entire volume in order to check whether your Steam path exists or not. I'd suggest doing something like this instead:

def try_to_get_steam_path():
	laufwerke = ["C:", "D:", "E:", "F:"]
	for lauf in laufwerke:
		steam_path = os.path.join(lauf, "SteamLibrary", "steamapps", "common")
		if os.path.exists(steam_path):
			return steam_path
	raise OSError("cannot find Steam path")

Your try_to_get_steam_path function does not return once it has found your Steam path. In addition,

steam_path = steam_path + r"\" + f"{game}"

expands the steam_path global variable more and more for each game, so you need to have another name for the target (e.g., game_path = steam_path + ...)
