Print the matrix element clockwise (Python implementation)

I think my algorithms are simpler and easier to understand than those on the web. As for the complexity of time, there is no comparison.

Algorithm idea: Traversing the matrix from the outermost to the inner layer

# My algorithm
Import Mathdef Print_matrix (matrix):    rec = [] # Store traversal element    rows = Len (Matrix)    cols = Len (matrix[0])    if rows &L T cols:        k = Math.ceil (ROWS/2)    else:        k = Math.ceil (COLS/2) for    N in range (k):  # Total number of loops        # the top row loop C10/>i = j = N while        J < cols:            rec.append (Matrix[i][j])            # Print (Matrix[i][j])            J + = 1        # Right-most column follow Ring        J-= 1        i + = 1 while        i < rows:            rec.append (Matrix[i][j])            # Print (matrix[i][j])            i + = 1< c22/># the bottom line loop        I-= 1 while        j > N:            J-= 1            rec.append (Matrix[i][j])            # Print (Matrix[i][j]) c28/># leftmost column loop while        i > n+1:            i-= 1            rec.append (Matrix[i][j])            # Print (matrix[i][j])        rows- = 1        cols-= 1    return rec
