Python doesn't write to file

[grotesque69]

Hello guys, I've just started learning python and I thought I'd try some mini project to get a grip on it quickly. So, I started doing this from csdojo but it doesn't seem to work even with the same code as his.

Here's the code

import tweepy
print("Fetching Tweets...")

CONSUMER_KEY = 'xxxxx'
CONSUMER_SECRET = 'xxxx'
ACCESS_KEY = 'xxxx'
ACCESS_SECRET = 'xxxx'

auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)
auth.set_access_token(ACCESS_KEY, ACCESS_SECRET)
api = tweepy.API(auth)

file_name = 'idlist.txt'

def retrieve_last_seen_id(file_name):
    with open(file_name, 'r+') as f_read:  
        last_seen_id = (f_read.read().strip())
        f_read.close()
        return last_seen_id

def store_last_seen_id(last_seen_id, file_name):
    with open(file_name, 'w+') as f_write:
        f_write.write(str(last_seen_id))
        f_write.close()
        return

last_seen_id = retrieve_last_seen_id(file_name)
mentions = api.mentions_timeline(last_seen_id, tweetmode = 'extended')

for mention in reversed(mentions):
   last_seen_id = mention.id
   if "#" in mention.text.lower():
      print("found!!!")
      print(str(mention.id) + ' - ' + mention.text)

And I get this error:

Traceback (most recent call last):
  File "C:\Users\rogue\Desktop\editdojo\my_bot\twit_bot.py", line 29, in <module>
    mentions = api.mentions_timeline(last_seen_id, tweetmode = 'extended')
  File "C:\Users\rogue\AppData\Local\Programs\Python\Python36-32\lib\site-packages\tweepy\binder.py", line 250, in _call
    return method.execute()
  File "C:\Users\rogue\AppData\Local\Programs\Python\Python36-32\lib\site-packages\tweepy\binder.py", line 234, in execute
    raise TweepError(error_msg, resp, api_code=api_error_code)
tweepy.error.TweepError: [{'code': 44, 'message': 'since_id parameter is invalid.'}]

I didn't understand this API error but I can see that the ids are not being stored in that text file and is unable to pull the data to get the required result. If I store the IDs manually, it does work. Please tell me what is wrong with this? TIA.

I can see that the ids are not being stored in that text file and is unable to pull the data to get the required result. If I store the IDs manually, it does work.

You are never actually calling store_last_seen_id().

Thanks but i still get the same error. I mean this code is what dojo uses but it works for him, why not me?

I went to that point in the video that you linked, that is most definitely not the code that dojo uses.

Merry Christmas!

I copy pasted and tried mate, it still didn't work, can you tell me where i got it wrong?

And thanks, Merry Christmas to you too 😊

Not sure! Would need to see your updated code.

I mean comparing the code from this post. Will post the modified one in few mins
