title: Python function: Find Change from purchase amount
body: <p>I'm looking for the most efficient way to figure out a change amount (Quarters, dimes, nickels, and pennies) from a purchase amount. The purchase amount must be less than $1, and the change is from one dollar. I need to know how many quarters, dimes, nickels, and pennies someone would get back. </p>
  
  <p>Would it be best to set up a dictionary?</p>
