Rotate any square matrix clockwise and anticlockwise in any degree of angle.

Project description

Rotate any square matrix clockwise and anticlockwise in any degree of angle.

matrix-rotation is a simple package for rotating elements of any square matrix in clockwise and anticlockwise direction. This rotation can be performed with any degree of angle or step size. This version is most suitable for small size matrix.

Use in python code

Following are some of the sample examples to show the use of matrix_rotation package. This package has a function named rotate_matrix which essentially takes input 2 dimensional square matrix as a first argument, degree as a second argument to determine the step size and default clockwise rotation as the final argument. print_rotate_matrix function is just the extension of rotate_matrix function which print the original matrix and rotated matrix on the console. Let's take a look.

>> from matrix_rotation import rotate_matrix, print_rotate_matrix

>>> matrix = [['a', 'b', 'c'],\
              ['h', 'i', 'd'],\
              ['g', 'f', 'e']]

>>> rotated_matrix = rotate_matrix(matrix, degree=2, clockwise=True)

>>> rotated_matrix 
[['g', 'h', 'a'], ['f', 'i', 'b'], ['e', 'd', 'c']]

>>> rotated_matrix = print_rotate_matrix(matrix, degree=2, clockwise=True)

Original Matrix:
[['a', 'b', 'c'],
['h', 'i', 'd'],
['g', 'f', 'e']]

Clockwise Rotated Matrix with Degree = 2:
[['g', 'h', 'a'],
['f', 'i', 'b'],
['e', 'd', 'c']]

>>> rotated_matrix
[['g', 'h', 'a'], ['f', 'i', 'b'], ['e', 'd', 'c']]

Use in command line interface (CLI)

matrix_rotation --help

Usage: matrix_rotation [OPTIONS]

  -M, --matrix TEXT           Use to show default examples of matrix rotation.
                              Otherwise use the input matrix from command
                              line. Input example : [["a", "b"],["d", "c"]]

  -D, --degree INTEGER        Degree of rotation. Can rotate matrix in between
                              0 degree to 360 degree.  [default: (1)]

  -C, --clockwise BOOLEAN     Use True to rotate matrix in a clockwise
                              direction. False for rotation in anticlockwise
                              direction.  [default: (True)]

  -S, --print_matrix BOOLEAN  Use True to show the result of Original and
                              Rotated Matrix.  [default: (False)]

  --help                      Show this message and exit.
