I was trying to get the concept of threading.Lock() on python but can't really figure out how it work with the two method acquire() and release()

Can some explain in details how to use it effectively and when to use?

When creating app that run multiple processes(threads). There are chances that two or more threads may access one variable, which may lead to data leakage, to avoid this, you have to synchronize access to such variable.
Meaning you have to lock it and give key to a thread, to maintain linear access.

Thanks so much... Got it,but is process the same as thread?

I think this should explain it. Thread uses the same shared memory within a process. While process uses different memory(global) space.
But they are basically the same. and multiple process could need to access one resources and synchronization will need to make proper use of resources. Same for threads try to access a global memory space in a process. The idea is the same.

I will suggest you also go through this post on StackOverF as well; https://stackoverflow.com/questions/3044580/multiprocessing-vs-threading-python
