Cannot use concurrent.futures.ThreadPoolExecutor() within a for loop, it dosent work after first iteration.
Please don’t post images of text.
Please include a traceback, just saying “it does not work” makes it hard to help you.
Your code breaks after the first loop because your
args is a generator object. Generators can be iterated over only once, after that they are exhausted. Try making
args a list instead, by replacing the outermost parentheses in the comprehension with brackets.
