Hi @Carolinewk, no worries.
There are two main requirements actually:

1. You need to get access to Twitter API, navigate http://apps.twitter.com/ and create an app from your account. You'll then need to fill some basic information but this operation is quite straightforward. Upon success, you'll get 4 elements (consumer_key, consumer_secret, access_token, access_token_secret). Replace with the corresponding values in lines 15-19, make sure you are the only one to know the values.
2. You need to download your personal twitter archive. For this, please see https://help.twitter.com/en/managing-your-account/how-to-download-your-twitter-archive. Once downloaded, you'll get a zip file, unzip it and extract a file named tweet.js located in data/.

Once you completed these 2 steps you'll just have to configure and run the script above.
Are you using windows ?

Yeah. I'm using windows. Actually I did everything and the keys are already with me. I just can't run the code haha, pretty stupid but It still very confusing to me (I have no experience with python).

I think it's supposed to configure it with IDLE, right? I just put the keys there.
I created a folder, put your script there (deloldtweets.py), edited it with the IDLE (putting the keys in the beginning), and finally, put the tweet.js file there.

So, in the folder there's only these 2 files. But I don't know how to run them. I tried CMD and Powershell. With cmd: I put (cd + folder location) and then python deloldtweets.py. It didn't work. And with powershell I did the same. Nothing happens :(

Sorry if it's not clear.

Okay, it might be tricky as I don't have a Windows machine on hand.
Basically you're all set once you have defined the parameters in lines 15-19 and put the tweet.js file in the same directory.
Can you try running execfile('deloldtweets.py') from the IDLE shell?
