body: <p>Basic stuff I know...;-P But what is the best way to check if a function returns some values?   </p>
  
  <pre><code>def hillupillu():
      a= None
      b="lillestalle"
      return a,b
  
  if i and j in hillupillu(): #how can i check if i or j are empty? this is not doing it of course;-P
      print i,j 
  </code></pre>
