hello,my name is
john,john, mary

Answer 1

You have been advised to use re.split() already; however, regular split() method of str should suffice as well:

with open('new_file', 'w') as f_out, open('my_file') as f_in:
    for line in f_in:
        new_str = ','.join(line.split(',')[1:])
        f_out.write(new_str)
