except that if you're joining a very long string, you'll have python 
copy the whole string again.

better to just redirect print
print >> fobj, '\n'.join(all)

but since this is a file object we're talking about, you can write while 
getting user input.

with open(...) as fobj:
     entry = ''
     while entry != '.'
         fobj.write(raw_input())
