Answer 1

If you're just replacing commas with colons, you don't need to use a csv parser at all.

with open("file.csv", 'r') as f:
    with open("temp.csv", 'w') as t:
        for lines in f:
            new_line = line.replace(",",":")
            t.write(new_line)

The only caveat is that you can't have commas elsewhere in the csv file.
