Question

1)def toggle_cell(row, column, cells):

• Return value: Flip the cell in the column of row from alive to dead or vice versa. Return True if the toggle was successful, False otherwise. • Assumptions: o cells will be a two-dimensional list with at least one row and one element in that row. o row and column are index values of cells • Notes: o Cells is being edited in place. Note that the return value is a Boolean and not a list. o Row and column might not be valid indexes of cells ▪ Hmmm… what might be useful to use here?

• Examples:

toggle_cell(0, 0, [[1,1],[1,1]]) → True

toggle_cell(-1,0, [[1,1],[1,1]])→ False

2) def is_valid(row, column, cells):

• Return value: True if the row and column are valid indexes of cells, False otherwise • Assumptions: o cells will be a two-dimensional list with at least one row and one element in that row. ▪ No inner lists will be empty. o For the purposes of this function (and project,) negative index values are considered invalid. • Notes: The tests for this function are hidden.

• Examples:

is_valid(0,0,[[0,0,0], [0,0,0]]) → True

is_valid(3,3,[[0,0,0], [0,0,0]]) → False

is_valid(-1,0,[[0,0,0], [0,0,0]]) → False

python help please

Answer 1

Solution to 1:

def toggle_cell(row, column, cells):
    if row >= 0 and column >= 0 and row <= len(cells) - 1 and column <= len(cells[0]) - 1:
        if cells[row][column] == 0:
            cells[row][column] = 1
        else:
            cells[row][column] = 0

        return True
    else:
        return False


print(toggle_cell(0, 0, [[1, 1], [1, 1]]))
print(toggle_cell(-1, 0, [[1, 1], [1, 1]]))

Output:
