Question

I’m trying to display a python 2D list without the commas, brackets, etc., and I’d like to display a new line after every ‘row’ of the list is over.

This is my attempt at doing so:

ogm = repr(ogm).replace(',', ' ')
ogm = repr(ogm).replace('[', ' ')
ogm = repr(ogm).replace("'", ' ')
ogm = repr(ogm).replace('"', ' ')
print repr(ogm).replace(']', ' ') 

This is the input:

[[0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [1, 1, 0, 1, 0, 0, 0, 0, 0, 0], [1, 1, 1, 0, 0, 0, 0, 0, 0, 0], [0, 1, 1, 0, 0, 0, 0, 0, 1, 1], [0, 0, 0, 0, 0, 0, 1, 1, 1, 0], [0, 0, 0, 1, 1, 0, 1, 1, 1, 1], [0, 0, 1, 1, 0, 0, 1, 1, 1, 1], [0, 1, 0, 0, 0, 0, 0, 1, 1, 0], [0, 0, 0, 0, 0, 0, 1, 1, 0, 0], [1, 0, 1, 1, 1, 1, 0, 0, 0, 0]]

This is the output:

"'    0  0  0  0  0  0  0  0  0  0    1  1  0  1  0  0  0  0  0  0    1  1  1  0  0  0  0  0  0  0    0  1  1  0  0  0  0  0  1  1    0  0  0  0  0  0  1  1  1  0    0  0  0  1  1  0  1  1  1  1    0  0  1  1  0  0  1  1  1  1    0  1  0  0  0  0  0  1  1  0    0  0  0  0  0  0  1  1  0  0    1  0  1  1  1  1  0  0  0  0    '"

I’m encountering two problems:

1. There are stray " and ‘ which I can’t get rid of
2. I have no idea how to do a newline

Answer 1

Simple way:

for row in list2D:
    print " ".join(map(str,row))
