如何创建和使用在线程内部用的全局对象

'''
threading.local()
local类用于创建一个全局对象，不过改该对象只能在线程内部使用，也就是说吗，全局是针对一个线程而言的
'''
import threading
import time

a = threading.local()

def worker(): a.x = 0 for i in range(20): time.sleep(0.01) a.x += 1 print(threading.current_thread(), a.x)


if __name__ == '__main__': for i in range(10): threading.Thread(target=worker).start()
