Continue

Discards the current iteration, and restarts the loop using the next item.

>>> for x in range(6):
...     if x == 3:
...             continue
...     print(x)
...

####Continue is great for cleaning code with lots of conditions:

#####Without continue:

for submission in submissions:
    if submission.author is not None:
        if submission.over_18 is False:
            if 'suggestion' in submission.title.lower():
                print('Found:', submission.id)

 

for submission in submissions:
    if submission.author is not None and submission.over_18 is False and 'suggestion' in submission.title.lower():
        print('Found:', submission.id)

#####With continue:

for submission in submissions:
    if submission.author is None:
        continue
    if submission.over_18:
        continue
    if 'suggestion' not in submission.title.lower():
        continue

    print('Found:', submission.id)

The mentality changes from "keep only the items with the right properties" to "discard the items with the wrong properties".
