title: How to write a python function that adds all arguments?
body: <p>I'd like to write a python function which adds all its arguments, using <code>+</code> operator. Number of arguments are not specified:</p>
  
  <pre><code>def my_func(*args):
      return arg1 + arg2 + arg3 + ...
  </code></pre>
