Delete All your Tweets

This script it based on @chrisalbon's original script, but instead of fetching the users timeline via the Twitter API it uses the archive of the users data to workaround the 3200 tweet limitation.

Setup

1. Create a virtualenv
2. Run pip install -r requirements.txt
3. Create a Twitter developer app.

Preparing the data

1. Download an archive of your Twitter data from Twitter. (link)
2. Copy data/tweet.js to your working directory and call the file all-tweets.json.
3. Remove the window.YTD.tweet.part0 = part of the first line of the file.

Running

1. Set the environment variables TWITTER_CONSUMER_KEY, TWITTER_CONSUMER_SECRET, TWITTER_ACCESS_TOKEN, and TWITTER_ACCESS_SECRET.
2. Run python wipe.py
3. ?
4. Profit

Potentail Improvements

• This process could be made faster with multiprocessing or threads to be faster.

Are you sure you actually managed to add all keys? That exception is only thrown if any are missing, in your case TWITTER_CONSUMER_KEY.

I'd suggest adding print(os.environ) on line 24 and checking the output carefully
