center all elements in the list output of 3x3 matrix in python

You can use the str.center(width) method to center each element in the list output of a 3x3 matrix in Python. Here's an example:

main.py
# Example matrix
matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

# Centering each element in the matrix
centered_matrix = [[str(element).center(5) for element in row] for row in matrix]

# Printing the centered matrix
for row in centered_matrix:
    print(row)
257 chars
10 lines

In this example, the str.center(width) method is used with a width of 5 to center each element in the matrix. The resulting centered matrix is then printed.

Output:

main.py
['  1  ', '  2  ', '  3  ']
['  4  ', '  5  ', '  6  ']
['  7  ', '  8  ', '  9  ']
84 chars
4 lines

Note that the width value should be large enough to accommodate the widest element in the matrix to ensure proper centering. Adjust the width value according to your specific matrix elements.

Hope this helps!
