Python中的同步(对象)？

import threading

# 创建一个锁
lock = threading.Lock()

# 共享资源
counter = 0

def increment():
    global counter
    for _ in range(100000):
        lock.acquire()
        counter += 1
        lock.release()

# 创建两个线程
thread1 = threading.Thread(target=increment)
thread2 = threading.Thread(target=increment)

# 启动线程
thread1.start()
thread2.start()

# 等待线程完成
thread1.join()
thread2.join()

print(f"Final counter value: {counter}")

import threading

lock1 = threading.Lock()
lock2 = threading.Lock()

def thread_1_task():
    with lock1:
        with lock2:
            print("Thread 1")

def thread_2_task():
    with lock1:  # 确保获取锁的顺序一致
        with lock2:
            print("Thread 2")

t1 = threading.Thread(target=thread_1_task)
t2 = threading.Thread(target=thread_2_task)

t1.start()
t2.start()

t1.join()
t2.join()
