I'm trying to understand whats the problem. I've already put

in_reply_to_status_id=tweet.id, auto_populate_reply_metadata=True

as documentation says, but still not working

I've found solution:

the line status = api.get_status(tweet.id) shouldn't be there. So every status.text.lower() should be tweet.text.lower()

But the most important, the code must work with strings instead of intergers on Id's, so every tweet.id stay

tweet.id_str

that consequently changes salva_id(max(ids_pegos)) to salva_id(ids_pegos[0])
