This script will delete all of the tweets in the specified account.
You may need to hit the "more" button on the bottom of your twitter profile
page every now and then as the script runs, this is due to a bug in twitter.

You will need to get a consumer key and consumer secret token to use this
script, you can do so by registering a twitter application at https://dev.twitter.com/apps

Thank you! this saved my day!
ps. can't install tweepy from thier latest version on github. must use pip install.

Nice script! I'm new to the twitter API. I deleted all tweets possible with this script, but that account still shows 8,5k tweets and all the tweets containing media (photos and videos) are available. The timeline of that account does not show up these tweets, that's why the method api,user_timeline does not retreive them. I'm not seeing anything in the documentation that helps me to get these tweets, maybe you have an idea?

I've made some changes on the script https://gist.github.com/JohnTroony/489ccc8e476b9377ae47

This can delete 1-2 tweets per second.

I forked this and made a much faster version of this using threads. It can delete upto 30-50 tweets per second.

Thank you!

Getting same problem which @argelouski reported. Account shows 8K tweets, none in the main timeline but all are there in "Replies" and "Media".

One approach would be to download your complete Twitter archive, extract tweet IDs from them and delete those.

I've tried this, and the forked version of this, and neither deletes any of my tweets. At least this version tells me that it cannot for about 28 instances, each followed by an 18-digit number, each beginning with 80xxxxxxxxxxxxxxxx. Any idea what's wrong and what to do to correct it?

I provided a secret key ,cunsomer key and verification code. But I don't how to run this script, Specialy I don't know where spread verification code.

Hey, if you are till looking for a script to delete all tweets you can check this one out : https://github.com/volshebnikRAJ/tweepy-api

Small suggestion for line 35- maybe also accept "y" in addition to "yes" with something like:

if do_delete.lower() == 'yes' or do_delete.lower() == 'y':
