I read the article on data driven programming that Danny linked too, and did
some additional looking around. I couldn't find anything directly using Python,
but I got an idea of the concept and went crazy with it. This may still be off
the mark, but I created a complex combination of lists and dictionaries to
represent each individual instance of each demonstrative (starting only with
one):
that_those = [ [ [ {'nom': 'ille', 'clue': 'That/Those, Singular, Masculine
Nominative'},
{'gen': 'illīus', 'clue': 'That/Those,
Singular, Masculine Genitive'},
{'dat': 'illī', 'clue': 'That/Those, Singular,
Masculine Dative'},
{'acc': 'illum', 'clue': 'That/Those, Singular,
Masculine Accusative'},
{'abl': 'illō', 'clue': 'That/Those, Singular,
Masculine Ablative'} ], [{'nom': 'illī', 'clue': 'That/Those, Plural, Masculine
Nominative'},
{'gen': 'illōrum', 'clue': 'That/Those, Plural, Masculine
Genitive'},
{'dat': 'illīs', 'clue': 'That/Those, Plural, Masculine
Dative'},
{'acc': 'illōs', 'clue': 'That/Those, Plural, Masculine
Accusative'},
{'abl': 'illīs', 'clue': 'That/Those, Plural, Masculine
Ablative'} ] ], [ [ {'nom': 'illa', 'clue': 'That/Those, Singular, Feminine
Nominative'},
{'gen': 'illīus', 'clue': 'That/Those, Singular, Feminine
Genitive'},
{'dat': 'illī', 'clue': 'That/Those, Singular, Feminine
Dative'},
{'acc': 'illam', 'clue': 'That/Those, Singular,
Feminine Accusative'},
{'abl': 'illā', 'clue': 'That/Those, Singular,
Feminine Ablative'} ], [ {'nom': 'illae', 'clue': 'That/Those, Plural, Feminine
Nominative'},
{'gen': 'illārum', 'clue': 'That/Those, Plural,
Feminine Genitive'},
{'dat': 'illīs', 'clue': 'That/Those, Plural, Feminine
Dative'},
{'acc': 'illās', 'clue': 'That/Those, Plural,
Feminine Accusative'},
{'abl': 'illīs', 'clue': 'That/Those, Plural, Feminine
Ablative'} ] ]
, [ [ {'nom': 'illud', 'clue': 'That/Those, Singular, Neuter Nominative'},
{'gen': 'illīus', 'clue': 'That/Those, Singular, Neuter
Genitive'},
{'dat': 'illī', 'clue': 'That/Those, Singular, Neuter
Dative'},
{'acc': 'illud', 'clue': 'That/Those, Singular, Neuter
Accusative'},
{'abl': 'illō', 'clue': 'That/Those, Singular, Neuter
Ablative'} ], [ {'nom': 'illa', 'clue': 'That/Those, Plural, Neuter
Nominative'},
{'gen': 'illōrum', 'clue': 'That/Those, Plural, Neuter
Genitive'},
{'dat': 'illīs', 'clue': 'That/Those, Plural, Neuter
Dative'},
{'acc': 'illa', 'clue': 'That/Those, Plural, Neuter
Accusative'},
{'abl': 'illīs', 'clue': 'That/Those, Plural, Neuter
Ablative'} ] ] ]
Now, this is a big mess, for sure, but it seems possible that it is abstract
enough that I could reuse the same logic and just switch out the data to make
different types of similar programs. Also, I can write a script to populate
this structure to construct a program to drill any type of word that is
declined by gender, number and case. I can call each item pretty easily like
this:
question_to_be_dispalyed_to_user =
that_those[gender][number][q_and_a]["clue"]
answer_to_that_question = that_those[gender][number][q_and_a][case]
Where gender, number, q_and_a, and case follow Peter's suggestion:
cases = ['nom', 'gen', 'dat', 'acc', 'abl']
case = random.choice(cases)
The complete code will follow, but I have a spooky new problem. When I try to
run the following code, I intermittently get the following error:
Traceback (most recent call last):
File "./latDemTest.py", line 59, in <module>
answer = that_those[gender][number][q_and_a][case]
KeyError: 'abl'
I looked this error up online, and it seems the key error is generated when one
attempts to retrieve a value from a dictionary with a key that does not exist.
The problem is, it seems to me that the keys should in fact exist. The odd
thing is, the code returns this error sometimes, and sometimes it doesn't. I
did a bunch of trials, keeping track of which particular entries in the data
structures worked and which failed, and I discovered that they overlap. The
dictionary {'gen': 'illōrum', 'clue': 'That/Those, Plural, Neuter Genitive'}
for example, happily spits out the proper question and answer sometimes, other
times it shoots out the previously mentioned error. I cannot understand how
this could happen!

# Don't forget ./ before filename to run from cmnd line!
