python多进程编程-死锁和递归锁（三）

import threading

# 创建递归锁对象
lock = threading.RLock()

def function(count):
    # 获取锁
    lock.acquire()
    print('Function', count, 'acquired lock')
    
    if count > 1:
        # 调用自身，递归调用
        function(count-1)
    
    # 释放锁
    lock.release()
    print('Function', count, 'released lock')

# 创建线程
thread = threading.Thread(target=function, args=(5,))

# 启动线程
thread.start()

# 等待线程结束
thread.join()
