title: Best way to split a list into randomly sized chunks?
body: <p>I have a list of numbers such as [5000, 5000, 5000, 5000, 5000, 5000]</p>
  
  <p>I need to create a function that turns that list into a list of randomly sized smaller lists, such as</p>
  
  <p>[[5000, 5000], [5000, 5000, 5000], [5000]]</p>
  
  <p>What's the best way to do this in python?</p>
