How to print a matrix using Python [duplicate]

Question

I am trying to create a matrix and then print it using python with the following expected output:

0 0 0 0
0 0 0 0
0 0 0 0
0 0 0 0

The code follows:

    matrix=[[]]
    matrix = [[0 for x in range(4)] for x in range(4)]
    print matrix

But the output comes as:

[[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]]

Please tell me why I'm getting this type of output and help with the correct one

Answer 1

What you are getting is the correct representation of a matrix. You have created a list that contains 4 lists, each list containing 4 '0's. If you want to print it differently then you have some options, but what you are printing is the representation of the above mentioned data structure.

for row in matrix:
  print ' '.join(map(str,row))

this should work for you.
