Callback URL for twitter app

[Truman]

I'm trying to create my first twitter app and ran to a wall that is called a callback url/
on twitter website this is an explanation:
https://developer.twitter.com/en/docs/ba...lback-urls

But that doesn't tell me much. Do you have any idea how this url should look like? I don't see it on my developer.twitter.com dashboard.

Should I have my own personal web site?

this is how basic code should look but I need to creat app first

from twitter import Twitter, OAuth

t = Twitter(auth=OAuth(<Access Token>,<Access Token Secret>, <Consumer Key>,<Consumer Secret>))
pythonTweets = t.search.tweets(q = "#python")
print(pythonTweets)
