python 全局变量的疑问

[C墨羽]

paidui_ally = []
paidui_enemy = []
is_ally_paidui = 0
is_enemy_paidui = 0

def paidui_set(faction):
    global is_ally_paidui
    global is_enemy_paidui

    if faction == "ally":
        global is_ally_paidui
        is_ally_paidui = 1
        print("paidui set: ", is_ally_paidui)
    elif faction == "enemy":
        global is_enemy_paidui
        is_enemy_paidui = 1
        print("paidui set: ", is_enemy_paidui)

def catchchat(faction):
    global paidui_ally
    global paidui_enemy
    global is_ally_paidui
    global is_enemy_paidui

    print("chat translation:", faction, is_ally_paidui, is_enemy_paidui, len(paidui_enemy))
    if faction == "ally" and is_ally_paidui == 1:
        paidui(faction, 1, 1)
    elif faction == "enemy" and is_enemy_paidui == 1:
        paidui(faction, 1, 1)
    elif faction == "ally" and len(paidui_ally) == 0:
        spawn_mob(faction, 1, 1)
    elif faction == "enemy" and len(paidui_enemy) == 0:
        spawn_mob(faction, 1, 1)

我定义了4个全局变量，通过paidui_set方法更改全局变量中的是否排队变量is_ally_paidui和is_enemy_paidui，当我执行过paidui_set方法之后，catchchat方法获取到的全局变量却是没有改变的全局变量！？有大佬知道为什么这个全局变量没有被改变吗？？
注：（catchchat方法是在一个线程中调用的）
 

self.ws_connect = websocket.create_connection(wss_url, header=headers)
self.read_thread = threading.Thread(target=self.read)
self.read_thread.start()

def read(self):
    while True:
        self.parse_message(msg)
        ...
def parse_message(self, msg):
    ...
    self.parse_chat_msg(msg.payload)
    ...
def parse_char_msg(self, msg_payload):
    from ch2 import catchchat
    catchchat("ally")
    ...

方法中的global只会跟着方法所在域走
