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])

Here is what the above code is Doing:
1. We have a list of lists, x.
2. We iterate over each list in x.
3. We iterate over each element in each list in x.
4. We print each element in each list in x.
