numpy iterate over 2d array rows with index code example

Example 1: iterating over 2d array python

x = [ ['0,0', '0,1'], ['1,0', '1,1'], ['2,0', '2,1'] ]
for i in range(len(x)):
  for j in range(len(x[i])):
    print(x[i][j])

Example 2: iterate over rows in numpy matrix python

import numpy
m = numpy.ones((3,5),dtype='int')
for row in m:
  # do stuff with row
