Hi, I am trying to help so far I got to: the google drive link gives me "You need access" and it would be easier to read your code snippet here on the post if you put them inside triple backticks. That would show the code verbatim. (This is how it is done in Markdown.)
Now one of your comments
# quantos amigos o usuário tem?that staretd with a hashmark turned into a title in your post.An alternative would be to post the code on gist.github.com/ and posting the link, but IMHO learning Markdown would be more valuable.
In addition it would be easier to help if you also included the error message you received.
I see your code has
Though in the original post the double underscores were eaten by the lack of the 3 backticks I mentioned at the beginning.
That is only necessary if you use Python 2 but would like to have the division behavior of Python 3. Which version of Python do you use?
Hello. Thank u. It was very helpful
