Use sys.excepthook to hook a function you define and in that function print a traceback and pause before exiting. Something like (not tested but copied from working example): import sys def Myexcepthook(type, value, traceback): print "in Myexcepthook-type=", type," value=",value," traceback=",

Re: Why anonymity? [was Re: map/filter/reduce/lambda opinions andbackground unscientific mini-survey]

The difference in readability between func = lambda x: x**3 - 5*x def func(x): return x**3 - 5*x def func(x): return x**3 - 5*x is obviously a matter of personal vision. The fuctional difference (and, I believe, the only difference) is that the def form attaches the specific name 'func' t

Re: Calculating average time

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 print
