Are Generators Threadsafe?

Question

I have a multithreaded program where I create a generator function and then pass it to new threads. I want it to be shared/global in nature so each thread can get the next

Answer 1

It depends on which python implementation you're using. In CPython, the GIL makes all operations on python objects threadsafe, as only one thread can be executing code at any given time.
