Answer 1

If lines is the list of your original text than it should be

for i in range(1,len(lines)):
    lines[i] = lines[i].split(',')

new_lines = []
for i in range(len(lines[0])):
    new_lines.append("%s,%s,%s" % (lines[0][i], lines[1][i], lines[2][i]))

or use csv Python module - http://docs.python.org/library/csv.html
