My apologies, I didn't express my self clearly enough (I was typing it at 3am). What I wanted to say that: this code is much clear and easier to understand than "oneliner". When you have a team of 10 developers working togather it is imortant so everyone understends code quikly.

Thank you for your comment, it was useful!

As a developer I would say this is one of the closest code that I would like to have submitted by my employees.
The one line code is not readable from first glace and not self explanatory.

it works in python 2, but not in 3

Can you please publish your code? This solution works fine for me, so I'm even eager to know what is the reason it doesn't work for you.

This looks like a great solution, however, I tried this on my own machine and got the following error:

Traceback (most recent call last):
File "", line 1, in
TypeError: translate() takes exactly one argument (2 given)

Is there a piece of the solution missing?

I can't believe this could be done in so few lines. @warwickwang - would you mind walking us through your thinking here?
