title: Align left or right using a variable in .format()
body: <p>Make a variable, item, that points to a string, "car". Make a variable, cost, that points to 13499.99. Print out a line that has item in a left-justified area of 10 characters, and cost in a right-justified area of 10 characters with 2 decimal places and commas in the thousands place.</p>
  
  <pre><code>item = "car"
  cost = 99,999.99
  print('{:&lt;10} {:&gt;10}'.format(item, cost))
  </code></pre>
  
  <p>essentially this is the desired output
  car       13,499.99</p>
  
  <p>Clearly I am doing something wrong here...
  From what I can tell this is what I need to do to achieve the desired effect. I am new to coding and Stack Overflow so if this question has been answered, I apologize. If somebody could help me out, I would greatly appreciate it. Also this is python 3.5.</p>
