Python Reddit Submission Text Slicing

I'm using Reddit's PRAW to collect submissions. I want to be able to slice the text of the submission and save it into a variable to compare against a hardcoded number to remove every submission post that has a number greater than it in its title.

import praw
reddit = praw.Reddit(client_id = 'REDACTED',
                    client_secret = 'REDACTED',
                    username = 'REDACTED', password = 'REDACTED',
                    user_agent = 'REDACTED')
subreddit = reddit.subreddit('NumbersReddit')
new_numpost = subreddit.new(limit=10)

for submission in new_numpost :
    if not submission.stickied:
        print(50*'-')
        print('User: {} '.format(submission.author))
        print('Title: {}'.format(submission.title))
        print('URL: {}'.format(submission.url))

Using the code above as a starting point: After removing the stickied submissions, I want to get the first two characters of the title of the post (which are and always will be 2 numbers, ie 24) and compare that against a hardcoded number, such as 18, so it then removes all posts that start with numbers greater than 18.

The following should be the output:

User: Example1

Title: 18 Years and I haven't realised this before

URL: https://www.reddit.com/r/NumbersReddit/comments/example1

User: Example2

Title: 18 times I tried this but it was worth it

URL: https://www.reddit.com/r/NumbersReddit/comments/example2

User: Example3

Title: 18 people said dieting was enough for them

URL: https://www.reddit.com/r/NumbersReddit/comments/example3

Fix

Changed this:

for submission in new_numpost :
    if not submission.stickied:
        print(50*'-')
        print('User: {} '.format(submission.author))
        print('Title: {}'.format(submission.title))
        print('URL: {}'.format(submission.url))

To this:

for submission in new_numpost :
    if not submission.stickied:
        title_number = int(submission.title[:2])
        if title_number < 25:
            print(50*'-')
            print('User: {} '.format(submission.author))
            print('Title: {}'.format(submission.title))
            print('URL: {}'.format(submission.url))

To get the first n number of characters of any string do the following:

(Assuming your title is "18: Hello!")

my_title = '18: Hello!'
print(my_title[:2])

Results in:

18

So for you you'd do the following on your title line: print('Title: {}'.format(submission.title[:2]))

Assuming it's a string in there.

Once you have that, you can convert it to an integer like so (assuming we haven't sliced it yet):

title = int(title[:2])

Then you can do whatever comparison you want with the int.

Updated to further clarify answer:

It seems your full title comes from submission.title, so what you can do is create two variables based on that: One variable named title_number and another named title where title_number = int(submission.title[:2]) and title = submission.title and all you do is compare the title_number and if it is greater than whatever number you get print the title in your for loop otherwise ignore it.

For example (assuming submission.title is '18 Years and I haven't realised this before')

check_int = 17
for submission in new_numpost:
    title = submission.title
    title_number = int(submission.title[:2])
    if title_number > check_int:
       print(title)

Should result in:

18 Years and I haven't realised this before

Being printed out
