Do you want to be an interpreted language geek? Are you tired of getting entangled in the dense syntaxes? Does it irritate you to compile your code to machine language first? Are you looking for an easy-to-use scripting language? Well, Ruby is the best pick for you then!

Ruby is a smart, easy-to-use, functional, Object-Oriented programming language, which comes as a wondrous mix of Perl's scripting power, Pythonic capabilities and much more! As Matsumoto, creator of Ruby, implies: "I hope to see Ruby help every programmer in the world to be productive, and to enjoy programming, and to be happy. That is the primary purpose of Ruby language."

This introductory course will be providing you with hands-on practice with the support of a bunch of interactive illustrations, exercises and the integral topics of variables, built-in classes, objects, conditionals, blocks and much more!

Cool, right? Ready to dive into one of the most influential and demanding third generation programming language? Let's tune in!

Ruby: An Amateur's Pitch

## Problem Statement
There is a method on hashes that flips keys and values. Find that method on the
[Ruby documentation about Hashes](http://www.ruby-doc.org/core-2.2.0/Hash.html) and try to flip the keys and values of this hash:

$$$$
```ruby
dictionary = {
:one => 'uno',
:two => 'dos',
:three => 'tres'
}
```

The output should look like this:


```
{ 'uno' => :one, 'dos' => :two, 'tres' => :three }
```
