How would I setup the interpreter to take the DROP command? I've been
reading and searching all day but I haven't found anything close to what
I'm doing. I realize that using custom commands in this case is overkill
but in the end is used to make the users life easier. If anyone can
point me to some documentation I would be more than grateful.

I'm not sure I understand what you're doing, but maybe you'll find the
following somewhat useful:

>>import code
>>class MyInterpreter(c ode.Interactive Console):

.... def raw_input(self, prompt=None):
.... # override input function
.... while 1:
.... text = raw_input(promp t)
.... if text.startswith ("DROP"):
.... # deal with custom command
.... print "CUSTOM DROP COMMAND", text
.... else:
.... return text
....

>>i = MyInterpreter()
>>i.interact( )

hello

>>DROP something

CUSTOM DROP COMMAND DROP something

>>x = 10
>>y = 20
>>x + y

30

>>DROP something else

CUSTOM DROP COMMAND DROP something else
