Get Discord User info

userinfo.py

import requests, json

token = 'DISCORD_USER_TOKEN'
ids = 'TARGET_ID'

response = requests.get(
        url = f'https://discord.com/api/v9/users/{ids}', 
        headers = {
            'authorization': token,
        }
    )

print(json.dumps(response.json(), indent=4))

Could you explain how it works? how to do it ? What I need?

sorry i'm a newbie.
