title: How to exit a loop?
body: <p>I'm asking input from the user and wanted to check if he used the right letters to continue, I've wrote this code, but even when I write "y" or "n", it doesn't exit the loop, and I have no idea why:</p>
  
  <pre><code>while True:
      start = input("Want to start? (Y/n) ").lower()
      if start != 'y' or 'n':
          print("letter not accepted! Please write 'Y' to start or 'N' to exit!\n")
      else:
          break
  
  if start == "y":
      separate(players)
  else:
      print("Goodbye!")
  </code></pre>
