The rotate-matrix is an interesting new python module, which allows conversion of a matrix(2-D array) into either clockwise rotation or anti-clockwise rotation. It at present consists of only two methods. You can loop through these methods for ‘n’ number of rotations.
Installation
This module doesn’t come in-built with python but can be installed using the following command:
pip install rotate-matrix
Functions
1) clockwise(): As obviously the name suggests, this function is used to rotate the matrix clockwise.
Syntax: clockwise(matrix)
Parameter: Takes matrix as parameter which is of type list.
Return Value: passes the clock-wised rotated version of the matrix
Example:
Python3
import rotate_matrixmat = [[5, 2, 6], [8, 2, 9], [3, 6, 7], [3, 6, 2]]print(rotate_matrix.clockwise(mat)) |
Output:
[(6, 9, 7, 2), (2, 2, 6, 6), (5, 8, 3, 3)]
2) anti_clockwise(): This function of this module rotates the given matrix anti-clockwise.
Syntax: anti_clockwise(matrix)
Parameter: Takes matrix as parameter which is of type list
Return Value: passes the anti-clockwise rotated version of the matrix
Example:
Python3
import rotate_matrixmat = [[5, 2, 6], [8, 2, 9], [3, 6, 7], [3, 6, 2]]print(rotate_matrix.anti_clockwise(mat)) |
Output:
[(3, 3, 8, 5), (6, 6, 2, 2), (2, 7, 9, 6)]
