Try it and see. You'll probably be pleasantly surprised.

Note that you can use `str.upper` in map ...

/usr/bin> C:/Python24/python.exe -m timeit -s "strings = ['a']*1000"
"map(str.upper, strings)"
1000 loops, best of 3: 304 usec per loop

/usr/bin> C:/Python24/python.exe -m timeit -s "strings = ['a']*1000"
"[s.upper() for s in strings]"
1000 loops, best of 3: 331 usec per loop

Pretty damn close.
