Typeerror: 'githubiterator' Object Does Not Support Indexing

Using github3.py, I want to retrieve the last comment in the list of comments associated with a pull request and then search it for a string. I've tried the code below, but I get

Solution 1:

I'm pretty sure the first line of your code doesn't do what you want. You're trying to index (with [-1]) an object that doesn't support indexing (it is some kind of iterator). You've also go a list call wrapped around it, and a loop running on that list. I think you don't need the loop. Try:

comments = list(GitAuth.repo.issue(prs.number).comments())[-1]

I've moved the closing parenthesis from the list call to come before the indexing. This means the indexing happens on the list, rather than on the iterator. It does however waste a bit of memory, since all the comments get stored in a list before we index the last one and throw the list away. If memory usage is a concern, you could bring back the loop and get rid of the list call:

for comments in GitAuth.repo.issue(prs.number).comments():
    pass # the purpose of this loop is to get the last `comments` value

The rest of the code should not be inside this loop. The loop variable comments (which should probably be comment, since it refers to a single item) will remain bound to the last value from the iterator after the loop ends. That's what you want to do your search on.
