Here are a few different 2d collection combinations:
2D list of lists
num_pad = [[1, 2, 3],
[4, 5, 6],
[7, 8, 9],
["*", 0, "#"]]
2D list of tuples
num_pad = [(1, 2, 3),
(4, 5, 6),
(7, 8, 9),
("*", 0, "#")]
2D list of sets
num_pad = [{1, 2, 3},
{4, 5, 6},
{7, 8, 9},
{"*", 0, "#"}]
2D tuple of lists
num_pad = ([1, 2, 3],
[4, 5, 6],
[7, 8, 9],
["*", 0, "#"])
2D tuple of tuples
num_pad = ((1, 2, 3),
(4, 5, 6),
(7, 8, 9),
("*", 0, "#"))
2D tuple of sets
num_pad = ({1, 2, 3},
{4, 5, 6},
{7, 8, 9},
{"*", 0, "#"})
2D set of lists (NOT VALID)
num_pad = {[1, 2, 3],
[4, 5, 6],
[7, 8, 9],
["*", 0, "#"]}
2D set of tuples
num_pad = {(1, 2, 3),
(4, 5, 6),
(7, 8, 9),
("*", 0, "#")}
2D set of sets (NOT VALID)
num_pad = {{1, 2, 3},
{4, 5, 6},
{7, 8, 9},
{"*", 0, "#"}}
for row in num_pad:
for num in row:
print(num, end=" ")
print()
