# 1) Explore copying middle row then changing an item in the copy
digits = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

# print(digits)
# print(middleRow)

# 2) Explore copying 1st two rows then modifying the copy
digits = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

# print(firstTwo)

# print(digits)
# print(firstTwo)

# 3) Access single int, then change it
digits = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

# print(theFour)

# print(digits)
# print(theFour)

# 4) Access a list of basic types, but not one of the original sublists
# e.g. the 1st two ints in the first sublist
digits = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

# print(slice)

# print(digits)
# print(slice)

# 5) Access a list with a sublist of 3 turtle objects and another with 1 turtle object.
# Slice the 1st two ints in the first sublist
