Hello everyone.
I am having a good time programming with Python 3.3 and Pygame. Pygame
seems like the perfect platform for the kind of simple games that I want to
make.
Pygame indeed looks pretty good to me as well. But I haven't done
anything with it, so I can't give you specific Pygame advice.

So far, I have done this:
A1 = pygame.Rect(10, 12, 43, 43)
A2
A3
A4
B1
B2
etc.
This is a code smell in Python (or any reasonable language). I'd
suggest that instead of trying to have 200 separate global variables,
you have one, maybe called grid, as follows:
maxrows = 10
maxcols = 20
grid = []
for row in range(maxrows):
rowdata = []
for column in range(maxcols):
arg1 = ...
arg2 = ...
arg3 = ...
arg4 = ...
rowdata.append(pygame.Rect(arg1, arg2, arg3, arg4)
grid.append(rowdata)
Now, this can be done shorter with list comprehensions, but I figured
this would be clearer for you. I also may have the 10 and 20 reversed,
but you can work that out.
You'd need to make four formulae to get the four arguments to the Rect
call, using row and column respectively. Remember that row and column
will be numbered from zero, not from one.
But now, you can either address a single rect by
grid[4][8]
or you can do something to all of them, or to an entire row, or to an
entire column, pretty easily.
While you're testing your formulae, you might want to replace the
rowdata.append line with something like:
rowdata.append( (arg1, arg2, arg3, arg4) )
And perhaps your maxrows, maxcols might be lower while you're testing.
And you can just print grid to see how those arguments are looking.
