What is thread safety in iterators?

Thread safety in iterators refers to the ability of an iterator to be safely accessed by multiple threads simultaneously without leading to inconsistent or corrupted data.

Why is it important for iterators to be thread-safe?

It's important because if multiple threads modify or read from an iterator at the same time, it can lead to unpredictable behavior, crashes, or data corruption.

Can you give an example of a non-thread-safe iterator?

Sure! A common example is a simple list iterator in Python. If one thread is iterating over the list while another thread modifies it, it can cause errors.

How can I make my iterators thread-safe?

You can use synchronization mechanisms like locks or concurrent data structures that are designed to handle multi-threaded access.
