多线程 - 为何 python condition acquire 会阻塞线程？

Answer 1

Queue comes with its own lock

If you use another lock, it is easy to cause a deadlock~

Also, you need to change sleep to cond.wait(), so that notify() will work~

Answer 2

After reading the document for a long time, the RLock written above only has the reentrant feature in a thread
