title: How to reset all values in a dictionary
body: <pre><code>{"green": 0, "y3": 1, "m@tt": 0, "newaccount": 0, "egg": 0, "results": 0, "dan": 0, "Lewis": 0, "NewAccount2": 0, "testyear3": 1, "testyear6": 0, "NewAccount1": 0, "testyear4": 0, "testyear5": 0, "Matt1": 0, "swag": 1, "lewis": 1, "matt": 1, "notin": 0}
  </code></pre>
  
  <p>this is the dictionary defined as 'completeddict'.
  What I want to do, is to change ALL values no matter what they are called to 0. 
  However bear in mind that new account names will be added at any point as 'keys' so I cannot manually do "completeddict[green] = 0", "completeddict[lewis] = 0", etc etc.</p>
  
  <p>Is there any way to have python change ALL values within a dictionary back to 0?</p>
  
  <p>EDIT: Unfortunately I do not want to create a new dictionary - I want to keep it called 'completeddict' as the program needs to use the dictionary defined as 'completeddict' at many points in the program.</p>
