greg 1. Is there a better time function to use?
For this particular scenario I think time.time() is probably what you want:
cumulative = 0.0
n = 0
for link in links:
t = time.time()
ie.Navigate(link)
cumulative += time.time() - t
n += 1

Hello Alexandre,
People interested in CSP and python may also want to check Logilab's
constraint module which has been available from some time at:
http://www.logilab.org/projects/constraint/
Indeed! And please send us some notes comparing both. :-)
