title: Converting Snake Case to Lower Camel Case (lowerCamelCase)
body: <p>What would be a good way to convert from snake case (<code>my_string</code>) to lower camel case (myString) in Python 2.7?</p>
  
  <p>The obvious solution is to split by underscore, capitalize each word except the first one and join back together.</p>
  
  <p>However, I'm curious as to other, more idiomatic solutions or a way to use <code>RegExp</code> to achieve this (with some case modifier?)</p>
