Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

FizzBuzz one-liner in Python

A common programming question for interviewers to ask potential job candidates is to code "FizzBuzz". That is, if a number is divisible by 3, then it should display "Fizz". If a number is divisible by 5, it should display "Buzz". If it is divisible by both, then it should display "FizzBuzz". Otherwise, display the current number between 1 and 100.


There are 2 alternatives - vote for the best!

Comment by shadyabhi 275 weeks and 3 days ago

Comment by shadyabhi 275 weeks and 3 days ago

Why would an interviewer be impressed by a seeming entry for an obfuscated code contest? It would make more sense to write a clear code block as an example of code you and others would have to maintain.

Comment by DopeGhoti 275 weeks and 2 days ago

I never said an interviewer would be impressed with this. I only gave background to what the FizzBuzz problem is.
