Python. Code repeats several times because the command to execute it is different

I have patched up a Discord bot using Python and it is working fine already but there is one problem.

This code repeats itself several times, once for each category of posting and right now I have random, funny, sports, games and news, so you can see the redundancy it is and what it'll further become, if there's need to make more categories.

if '!random' in messageContent:
                channel = int(chanRandom.strip('"'))
                channel = client.get_channel(channel)
                while c < 50:
                    if messageContent == '!random':
                        submission = next(x for x in randomList[sortListHot] if not x.stickied)
                        sortType   = 'Hot sorting'
                    elif messageContent == '!random top':
                        submission = next(x for x in randomList[sortListTop] if not x.stickied)
                        sortType   = 'Top sorting'
                    elif messageContent == '!random new':
                        submission = next(x for x in randomList[sortListNew] if not x.stickied)
                        sortType   = 'New sorting'
                    with open(urlFile, 'r') as urlRead:
                        if str(submission.url) not in urlRead.read():
                            await channel.send(f"{submission.url}\n{submission.title}\n<https://reddit.com{submission.permalink}>")
                            await channel.send("-------------------------")
                            with open(urlFile, 'a+') as urlWrite:
                                urlWrite.write(str(f'{submission.url}\n'))
                            c += 2
                        else:
                            print(f'{messageContent} repost: {submission.url}')
                await channel.send(sortType)

My idea right now is to create a list with every possible command but the problem is posting in the correct channel with the variable channel = int(chanRandom.strip('"')), which changes in accord to the command used channel = int(chanNews.strip('"')) and so on.

There is also an issue with memory usage, because I think the bot is saving everything but there is no need to but this is something for another time.

Any help is appreaciated.
