title: While IF in Python - Looping if statements are incorrect
body: <p>Having some difficulty using a While function alongside an IF so that if an INPUT hasn't been met, the same question would be repeatedly asked until the outcome was correct.</p>
  
  <pre><code>county = input(str("County London/Kent/Essex: ")).upper()
  while county != ("LONDON") and county != ("KENT") and county != ("ESSEX"):
      if county == ("LONDON"):
          county = ("LONDON")
      elif county == ("KENT"):
          county = ("KENT")
      elif county == ("ESSEX"):
          county = ("ESSEX")
      else:
          county = input(str("Invalid - Please enter an accepted county: ")).upper()
  </code></pre>
  
  <p>If the user doesn't enter London, Kent or Essex, the input message would be asked until one of these are entered.</p>
