Final answer:
To create a 4x4 matrix in Python and traverse it row-wise and column-wise, you can use nested lists and for loops. The row-wise traversal can be done by iterating over each row in the matrix and printing each element. The column-wise traversal can be done by using the zip() function and iterating over each column.
Step-by-step explanation:
To create a 4×4 matrix, you can use nested lists in Python. Here is an example:
matrix = [[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], [13, 14, 15, 16]]
To traverse the matrix row-wise, you can use a nested for loop:
for row in matrix:
for element in row:
print(element, end=' ')
print()
To traverse the matrix column-wise, you can use zip() function along with the * operator:
columns = zip(*matrix)
for column in columns:
for element in column:
print(element, end=' ')
print()
