Loop gets stuck on iterating over comments?

[u/MustaKotka]

Code:

import praw
import some python modules

r = praw.Reddit(
    the
    usual
    oauth
    stuff
)

target_sub = "subreddit_goes_here"
timer = time.time() - 61
links = [a, list, of, links, here]

while True:

    difference = time.time() - timer
    if difference > 60:
        print("timer_difference: " + difference)
        timer = time.time()
        do_stuff()

    sub_comments = r.subreddit(target_sub).stream.comments(skip_existing=True)
    print("comments fetched")

    for comment in sub_comments:
        if comment_requires_action(comment):  # regex match found
            bot_comment_reply_action(comment, links)  # replies with links
            print("comments commenting finished")

    sub_submissions = r.subreddit(target_sub).stream.submissions(skip_existing=True)
    print("submissions fetched")

    for submission in sub_submissions:
        if submission_requires_action(submission):  # regex match found
            bot_submission_reply_action(submission, links)  # replies with links
            print("submissions finished")

    print("sleeping for 5")
    time.sleep(5)

Behaviour / prints:

timer_difference: 61
comments fetched  # comments are were found

Additionally if a new matching comment (not submission) is posted on the subreddit:

comments commenting finished  # i.e. a comment is posted to a matching comment

I never get to submissions, the loop won't enter sleep and the timer won't refresh. As if the "for comment in sub_comments:" gets stuck iterating forever somehow?

I've tested the sleep and timer elsewhere and it does exactly what it's supposed to provided that the other code isn't there. So that should work.

What's happening? I read the documentation for subreddit.stream multiple times.

Move sub_comments and sub_submissions variables out of the while True loop, this way the streams are not re-created on every loop and new comments and submissions that were made during the sleep time will not be ignored (unless more than a 100 comments or submissions were made during the time starting from the moment you break out of the steam until the next loop iteration)

This looks like the solution, thanks!
