Hey all,
I am writing a program to drill the user on Latin demonstrative
pronouns and adjectives (DPA). It displays a description, and the user
has to enter the DPA that corresponds to the description. DPA vary for
gender, number and case, and there are 3 separate DPA. I have these
stored in a bunch of dictionaries, with the DPA, gender and number in
the dictionary name and the cases as keys. Of course, the values are
the DPA themselves. Like so:
that_those_Masculine_Singular = {'nom': 'ille', 'gen': 'illīus',
'dat': 'illī', 'acc': 'illum', 'abl': 'illō'}
I have a function that randomly selects one of these dictionaries, and
another that randomly selects strings corresponding to the keys
('nom', 'gen', etc.). The trouble begins somewhere along here:
D = chooseDict()
c = chooseCase()
print(D, c)
guess = ''
# code to get the guess
# then,
answer = D[c]
if guess == answer:
# Do stuff, change score, continue, etc.
This doesn't work, and I get this error:
TypeError: string indices must be integers
So my question is, why does Python think that D is a string? When I
type the actual names (i.e., that_those_Masculine_Singular["nom"]) the
answer is returned just fine. I have tried D['c'] and D["c"] also, and
got the same error. I searched the web, and I can find no explanation
on how to do what I am doing, and I can find nothing that indicates
why this doesn't work. I'd really appreciate any help!
Thank you,
J

Assuming that it is the
answer = D[c]
statement is giving you the TypeError, I suggest you add the following
print statements just before it:
print("'D' is of type %s"%(type(D), )
print("'c' = %s and is of type %s."%(c, type(c), )
You might get some surprises.
