title: Call a function without waiting for it
body: <p>Hi I was wondering if there was a way of calling a function/method (preferably in Python or Java) and continue execution without waiting for it.</p>
  
  <p>Example:</p>
  
  <pre><code>def a():
      b()  #call a function, b()
      return "something"
  
  def b():
      #something that takes a really long time
  </code></pre>
