python的同步锁是什么类型

Question

如何使用isinstance判断一个变量是不是同步锁：
import _thread
import threading

lock = threading.Lock()
print(type(lock))

isinstance(lock,_thread.lock)

Answer 1

另外创建一个同步锁对象,判断两个对象的type是否相同,或者导入LockType好像也可以

from threading import Lock


l1 = Lock()
lock = Lock()
print(type(lock) == type(l1))

from _thread import LockType

print(isinstance(lock, LockType))
