Introduction: evaluator

We're making a web interface to an evaluation script. 

Trivial example: Suppose we start with a list like this...

    >>> letters = ['C', 'e', 'd', 'A', 'B', 'c', 'D', 'E', 'b', 'a']

And we want to end up with two lists:

    
    >>> good = ['C', 'A', 'B', 'D', 'E']
    >>> bad = ['e', 'd', 'c', 'b', 'a']

(For some reason we want the uppercase letters, not the lowercase.)

We iterate through the list, and classify them.

    >>> def isgood(letter): 
    ...  from string import ascii_uppercase
    ...  return letter in ascii_uppercase

    >>> for item in letters:
    ...  if isgood(item): good.append(item)
    ...  else: bad.append(item)

isgood() will be actually be done by the human user of the interface.
