title: python: force two zeroes after dot when converting float to string
body: <p>I am currently trying to force python to keep two zeroes after converting a float to a string, i.e.:</p>
  
  <p>150.00 instead of 150.0</p>
  
  <p>I am not very experienced with python and thus can only think of a brute force method to achieve this. Is there a built in functionality to do this?</p>
  
  <p>Thanks</p>
