title: Ruby/Rails: Converting a range into a hash
body: <p>What is the simplest way to convert the range <code>1..10</code> into a hash of the following format?</p>
  
  <pre><code>{
    1 =&gt; '£1',
    2 =&gt; '£2',
    # ...
  }
  </code></pre>
  
  <p>I have tried doing this with <code>map</code>, but end up with an array of hashes rather than a single hash.</p>
  
  <p>Thanks.</p>
