Is there a better way to chose a slice of a list?

week[2:5] # ;-)

If you want the interpreter to turn non-ints into ints for you, you will 
have to give it some sort of function or mapping to use.

dayint = {day:i for i,day in enumeratr(week)} # works in Py3 at least
week[dayint['tue']:dayint['fri']]

# or, untested, basing attrodic on memory of posted code

class attrodic(): #py3
   def __init__(self, dic):
     self.__dict__.update(dic)

di = attrodic(week)
week[di.tue:di.fri]

Most elegant, and most setup work ;-).
