Having gone through this myself recently (albeit not in idle), you
might try:

import profile
a=[]
prof = profile.Profile()
prof.runctx( 'f(a)', globals(), locals() )
prof.print_stats()

If that works, you can just define:

import profile
def runctx(statement, globals, locals, *args):
prof = profile.Profile()
try:
prof = prof.runctx( statement, globals, locals )
except SystemExit:
pass
if args:
prof.dump_stats(args[0])
else:
return prof.print_stats()

and then subsequently use:

a=[]
runctx( 'f(a)', globals(), locals() )

Hopefully this convenience function will be added to profile.py in the next
version.
