title: How to read keyboard input?
body: <p>I would like to read data from the keyboard in Python. I tried this code:</p>
  <pre><code>nb = input('Choose a number')
  print('Number%s \n' % (nb))
  </code></pre>
  <p>But it doesn't work, either with eclipse nor in the terminal, it's always stop of the question. I can type a number but after nothing happen.</p>
