[Tutor] Creating Sudoku

[W W]

Actually, a dictionary might be a good idea.
I just played with this so youcan get a little picture.

>>> foo = {'1a': 3, '1b': 4}
>>> row = raw_input("Row: ")
Row: 1
>>> col = raw_input("Column: ")
Column: b
>>> val = raw_input("Value: ")
Value: 1
>>> foo[row+col] = val
>>> foo
{'1a': 3, '1b': '1'}

You could easily run int(val) to convert to the integer value to store
in the dict. The other benefit is that python ignores whitespace in
between dictionary elements, so you could do something to the effect
of

foo = {'1a': 1, '1b':2, '1c':3,
           '2a': 0, '2b': 9, '2c': 6}

Or something of similar nature.

I suppose in favor of a 2d list, the loop would be a little more
straighforward. With a dict, the pairs are in no particular order, so
you would have to basically create the same loop for a 2d array, and
then convert the values to strings.

Either way, good luck!

To be considered stupid and to be told so is more painful than being
called gluttonous, mendacious, violent, lascivious, lazy, cowardly:

ennoblement and exaltation, but stupidity hasn't. - Primo Levi
