title: Map function error in Python
body: <p>I tried to run the following code.</p>
  
  <pre><code>def fahrenheit(T):
      return (9.0/5)*T + 32
  
  temp = [2 , 43 , 54 , 67 , 78 , 89.9]
  
  map(fahrenheit,temp)
  </code></pre>
  
  <p>Why does map function prints</p>
  
  <pre><code>&lt;map at 0x15a6cf17550&gt;
  </code></pre>
