python nested loop for a 2D list
list = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
for i in range(0, len(list)): # loops over the external list
for j in range(0, len(list[i])): # loops over every internal list
print(list[i][j], end="\t") # prints the elements of the inner list seperated by a tab character
print("\n") # after every 3 iterations, print a new line/ shift to a new line
# OR you could use a much shorter way of writing the above nested loops
# either one you choose, the logic is the same for both
for i in list:
for j in i:
print(j, end="\t")
print("\n")
# Expected Output:
"""
1 2 3
4 5 6
7 8 9
"""
