title: How to convert from mm/dd/yyyy format to yyyy-mm-dd in python 3.0 when given 1/4/2014
body: <p>So the I generally understand how I would convert from mm/dd/yyyy format to yyyy-mm-dd if the initial date given was something like 01/04/2014. However I am only given 1/4/2014  (without zeroes). Is there a clean and more efficient way of converting this in python 3 rather than writing a bunch of if statements?</p>
