title: Python "append" function
body: <p>I'm having problems with adding accounts to mapping with function append.</p>
  
  <pre><code>mapp = ["example"]
  
  example1 = raw_input("Enter Username: ")
  if example1 in mapp:
      print "yay"
  else:
      print ("Forgot Username eh?")
      example = raw_input("Enter New Username: ")
      if example not in mapp:
          mapp.append(sana)
  </code></pre>
  
  <p>So as you can see from the script, if i enter username "example", program prints "yay".
  And if i type wrong i can create new "account" what i can use next time when i want my program to print "yay". But when i try to add new "account" it doesn't work. I don't get any error messages or anything but it just doesn't add new "account" to mapp. So any ideas ?</p>
