If you create an iterator, you will try to pass it between the threads. You can share objects by a Yaield iterator when it comes to a safe thread but Don Share the iterator Alone Across the boundaries of the fiber. For example, to create an iterator that produces letters from the belt after a second, you can do it:
data = "abcdefg"
d_iter = iter(data)
item = next(d_iter)
item2 = next(d_iter)
# ... etc.
In this example d_iter is an iterator object. You can share data and item (gold item2and etc.) between threads but you can’t share d_iter Alone Between the fibers, because it is likely to damage its inner condition.
Python Frame objects They contain information about the status of the program at a certain point of its design. Among other things, the Python tuning mechanisms are used to create details of the program when there is an error condition.
