Thanks Cédric Lucantis,
I will have to study some more;
os.open(filename, os.O_WRONLY | os.O_EXCL | os.O_CREAT)
Is over my head at this time.

With your suggestion I did come up with this;

#!/usr/bin/python

import os
import sys
filename = raw_input('Enter the filename: ')
if os.path.exists(filename):
    r = raw_input(
'Warning, file %s exists, overwrite it [y/n] ? ' % filename)
if r != 'y' : sys.exit(0)
fobj = open(filename, 'w')
yourname = raw_input('What is your name: ')
fobj.write(yourname)
fobj.close()
