In fact, in my test, the list comprehension won: $ /usr/lib/python2.4/timeit.py -s "import string; slist=['aB'*100 for i in range(100)]" "map(string.upper, slist)" 1000 loops, best of 3: 522 usec per loop $ /usr/lib/python2.4/timeit.py -s "slist=['aB'*100 for i in range(100)]" "[s.upper() for s in slist]" 1000 loops, best of 3: 461 usec per loop Dan -- http://mail.python.org/mailman/listinfo/python-list
