What is the difference between lock and rlock in Python?

Can you explain the difference between lock and rlock in Python?

Sure! In Python, a lock is a synchronization primitive that allows only one thread to access a resource at a time.

What about rlock? How is it different from a regular lock?

An rlock, or reentrant lock, allows a thread to acquire the lock multiple times without blocking itself.

So, can you give me an example of when to use rlock?

You would use an rlock when a thread needs to call a function that requires the same lock multiple times, preventing deadlocks.

Got it! Are there any performance differences between using lock and rlock?

Yes, rlocks can be slightly slower due to the additional bookkeeping required, but they are essential for avoiding deadlocks in certain scenarios.
