如何使我的变量变得全局，如何使程序等待到一定的条件？

global x
x = 10

def set_global_variable():
    globals()['x'] = 10

set_global_variable()

import time

while True:
    if condition:
        break
    time.sleep(1)  # 等待1秒后再次检查条件

import threading

condition = threading.Condition()

def wait_for_condition():
    with condition:
        condition.wait()  # 等待条件满足
        # 执行条件满足后的操作

def notify_condition():
    with condition:
        condition.notify()  # 通知条件满足

# 在需要等待条件的线程中调用wait_for_condition()
# 在满足条件的线程中调用notify_condition()
