I wrote a bot that fetches posts from Reddit and posts them on a Twitter Account. But sometimes - i dont know why - it posts twice in a row, and not once every 3 hours. I am suspecting that it is because i did something like this:

```
do stuff:
    if stuff doesnt already exist:
        do other stuff
    else:
        do stuff

```

And i really think its bad practice, but i cant figure out how else i can let it run in an infinite loop, but still try to get a post that hasnt been posted before.

I have two points in my code where i "re-run" the entire code upon a check. One is when the post that is fetched from reddit is not an image, the other when the post that was fetched was already posted before (and stored in a json file for this exact check).

I hope someone understands what i mean, thanks in advance.

```
import time
import tweepy
import datetime
import praw
import urllib.request
import os
import json

def Mainbot():
    reddit = praw.Reddit(client_id='X',
                          client_secret='X',
                          user_agent='RedditFetchBot by FlyingThunder')

    def Tweet(postinfo):
        auth = tweepy.OAuthHandler("X", "X")
        auth.set_access_token("X", "X")
        api = tweepy.API(auth)
        try:
            api.update_with_media("local-filename.jpg", postinfo)
        except:
            print("not a file post")
            Mainbot()            #check 1

    post = reddit.subreddit('okbrudimongo').random()
    x = post.id

    with open('data.json', 'r') as e:
        eread = e.read()
        if x not in eread:
            with open('data.json', 'a') as f:
                json.dump(x, f)
                f.close()
                e.close()
        else:
            e.close()
            print("already posted")
            Mainbot()      #check 2

    print(post.url + " " + post.title)
    urllib.request.urlretrieve(post.url, "local-filename.jpg")
    Tweet(postinfo=post.title+" (https://www.reddit.com" + post.permalink+")")
    try:
        time.sleep(5)
        os.remove("local-filename.jpg")
    except:
        print("Datei nicht vorhanden")

def loop():
    time.sleep(1800)
    print("still running")
    print(datetime.datetime.now())

while True:
    Mainbot()
    loop()
    loop()
    loop()
    loop()
    loop()
    loop()

```

By the way, here is what it gives back - i made print checks to see what goes wrong, here you can see what it says when it posts twice
