Delete (very) old tweets obtained from a twitter archive

deloldtweets.py

#!/bin/python3
# Largely copied from http://www.mathewinkson.com/2015/03/delete-old-tweets-selectively-using-python-and-tweepy
# However, Mathew's script cannot delete tweets older than something like a year (these tweets are not available from the twitter API)
# This script is a complement on first use, to delete old tweets. It uses your twitter archive to find tweets' ids to delete
# How to use it :
#     - download and extract your twitter archive (tweet.js will contain all your tweets with dates and ids)
#     - put this script in the extracted directory
#     - complete the secrets to access twitter's API on your behalf and, possibly, modify days_to_keep
#     - delete the few junk characters at the beginning of tweet.js, until the first '['   (it crashed my json parser)
#     - review the script !!!! It has not been thoroughly tested, it may have some unexpected behaviors...
#     - run this script
#     - forget this script, you can now use Mathew's script for your future deletions
