Help with Classes

[Lonewolf]

can i ask something?
For question 1 my exercise says : Set in all classes the appropriate methods to retrieve and store a new value for each class attribute.
How you do that?

as for the grid -it's not neseccary though -i could use something like that:

    grid = []
# row
for row in range(11):
    grid.append([])
#  column
for column in range(25):
    grid.append([])
