title: How do I determine input as an integer and the length, simultaneously?
body: <p>Ok so I'm really new to programming. My program asks the user to enter a '3 digit number'... and I need to determine the length of the number (make sure it is no less and no more than 3 digits) at the same time I test to make sure it is an integer. This is what I have:</p>
  
  <pre><code>while True:
      try:
          number = int(input("Please enter a (3 digit) number: "))
      except:
          print('try again')
      else:
          break
  </code></pre>
  
  <p>any help is appreciated! :)</p>
