title: SyntaxError invalid token
body: <p>I have a problem when I try to assign a value to a variable. The problem shows up when I try to put a date as a tuple or a list in this order: <code>year, month, day.</code></p>
  
  <pre><code>&gt;&gt;&gt; a = (2016,04,03)         # I try to put the date into variable 'a' as a tuple.
  SyntaxError: invalid token
  &gt;&gt;&gt; a = [2016,04,03]         # I try to put the date into variable 'a' as a list.
  SyntaxError: invalid token
