python-多線程共享全局變量

# 定義一個變量
nums = [11, 22]


def test1(nums):
    nums.append(33)
    print('-----------in test1 num={}---'.format(nums))


def test2():
    print('-----------in test2 num={}---'.format(nums))


def main():
    t1 = threading.Thread(target=test1, args=(nums,))  # args 傳遞參數，要用元組的形式
    t2 = threading.Thread(target=test2)

    t1.start()

    t2.start()
    time.sleep(1)

    print('-----------in main Thread num={}---'.format(nums))
