print matrix in spiral form python

Python program for Spiral traversal of matrix. Here problem description and explanation.

#  Python 3 program for 
#  Spiral form of matrix
class SpiralView :
	def spiral(self, data, startRow, 
               startCol, endRow, endCol, element) :
		i = startCol
		#  Left to right
		while (i <= endCol and element > 0) :
			element -= 1
			print("", data[startRow][i], end = " ")
			i += 1
		
		i = startRow + 1
		#  Top to down
		while (i <= endRow and element > 0) :
			element -= 1
			print("", data[i][endCol], end = " ")
			i += 1
		
		i = endCol - 1
		#  Bottom right to bottom-left
		while (i >= startCol and element > 0) :
			element -= 1
			print("", data[endRow][i], end = " ")
			i -= 1
		
		i = endRow - 1
		#  Bottom left to top
		while (i > startRow and element > 0) :
			element -= 1
			print("", data[i][startRow], end = " ")
			i -= 1
		
		if (startRow + 1 <= endRow - 1 and element > 0) :
			#  Recursive call
			self.spiral(data, startRow + 1, startCol + 1, 
                        endRow - 1, endCol - 1, element)

	task = SpiralView()
	#  Given matrix
	matrix = [
		[1, 2, 3, 4, 5, 6],
		[22, 23, 24, 25, 26, 7],

	col = len(matrix[0])
	#  Get the number of element
	element = row * col
