@rdrtx1: nice! works!

But: the ./.:9 only works because it's the last value pair operated upon, gsubbing each and every entry that has not been changed before, as it's using two . wild cards. Escape at least one of them to be on the safe side.

Not sure if its actually a dot or any value not previously matched gets a nine. Escape or not to escape. That is the question. Use as needed.

I think I figured it out by changing the last line in your code to:

Code:
print(*columns, sep='    ', file=open("output.txt", "a"))

Any problems with doing this?
The issue with that is that the file output.txt is opened on every row and appended to it.

Another way would be to use the shell redirection of stdout
Code:
python3 conv.py > output.txt

From the program itself it could be like:

Code:
convertion_table = { '0/0': 0, '0/1': 1, '1/1': 2, './.': 9 }
with open('columns_by_rows.file') as read_f:
    with open('output.txt', 'w') as write_f:
        for line in read_f:
            columns = [convertion_table[f] for f in line.split()]
            row = '    '.join([str(n) for n in  columns]) + '\n'
            write_f.write(row)
