Should you create an iterator, don’t try and cross it between threads. You may share the objects yielded by an iterator, so long as they’re thread-safe, however don’t share the iterator itself throughout thread boundaries. As an illustration, to create an iterator that produces the letters from a string one after the opposite, you can do that:
knowledge = "abcdefg"
d_iter = iter(knowledge)
merchandise = subsequent(d_iter)
item2 = subsequent(d_iter)
# ... and many others.
On this instance, d_iter is the iterator object. You would share knowledge and merchandise (or item2, and many others.) between threads, however you’ll be able to’t share d_iter itself between threads, as that’s prone to corrupt its inner state.
Python body objects include details about the state of a program at a specific level in its execution. Amongst different issues, they’re utilized by Python’s debugging mechanisms to provide particulars about this system when an error situation arises.
