All you do is:
self.GetCellValue(row, column)
Where self is a wxGrid class instance.
Sample class from working program:
class SimpleGrid(wxGrid): ##, wxGridAutoEditMixin):
def __init__(self, parent):
wxGrid.__init__(self, parent, -1)
#
# Get shortcuts to some editors for different types of cells
#
bEditor=wxGridCellBoolEditor()
bRenderer=wxGridCellBoolRenderer()
tEditor=wxGridCellTextEditor()
tRenderer=wxGridCellStringRenderer()
fEditor=wxGridCellFloatEditor()
fRenderer=wxGridCellFloatRenderer()
fRenderer.SetPrecision(2)
#
# Define and set the column sizes and labels
#
# Display
#--Column Heading, Width, Alignment,read-only, editor, renderer
self.columndefs=(
("?", 20, wxALIGN_LEFT, false, bEditor, bRenderer),
("Cust#", 50, wxALIGN_LEFT, true, tEditor, tRenderer),
("Cust Name", 180, wxALIGN_LEFT, true, tEditor, tRenderer),
("Reference", 100, wxALIGN_LEFT, true, tEditor, tRenderer),
("DocType", 50, wxALIGN_CENTRE,true, tEditor, tRenderer),
("Inv. #", 75, wxALIGN_CENTRE,true, tEditor, tRenderer),
("InvDate", 60, wxALIGN_CENTRE,true, tEditor, tRenderer),
("L#", 35, wxALIGN_CENTRE,true, tEditor, tRenderer),
("Item #", 65, wxALIGN_CENTRE,true, tEditor, tRenderer),
("Description",300, wxALIGN_LEFT, false, tEditor, tRenderer),
("Qty", 50, wxALIGN_RIGHT, false, tEditor, tRenderer),
("Price", 50, wxALIGN_RIGHT, true, fEditor, fRenderer),
("Cost", 50, wxALIGN_RIGHT, true, fEditor, fRenderer),
("OMMC?", 60, wxALIGN_CENTRE,false, tEditor, tRenderer),
("OMMC $", 70, wxALIGN_RIGHT, false, tEditor, tRenderer),
("S#", 35, wxALIGN_CENTRE,false, tEditor, tRenderer),
("Serial #'s", 300, wxALIGN_LEFT, false, tEditor, tRenderer)
)
self.columncount=len(self.columndefs)
self.CreateGrid(0, self.columncount)
#
# Set column widths
#
map(self.SetColSize, range(self.columncount),

Hope it helps. I pretty much got this from the wxWindows demos
that come with standard installation.
