How do I handle shared data in multiprocessing?

In Python, you can use the multiprocessing module, which provides shared memory objects like Value and Array.

Can you explain how to use Value for shared data?

Sure! Value allows you to create a shared variable that can be accessed by multiple processes. You define it like this: shared_value = Value('i', 0) for an integer.

What about using Array? How does that work?

Array is similar to Value, but it allows you to create a shared array. You can define it like this: shared_array = Array('i', [0, 1, 2]).

Are there any synchronization issues I should be aware of?

Yes, when multiple processes access shared data, you should use locks to prevent race conditions. The Lock class in multiprocessing can help with that.
