Dear Ian, thank you for you kind response. I was pretty confident the issue had already been discussed, but I was unable to look it up.
I suppose your "filter" syntax is the best given the options (I always forget about map and filter...) and definitely I see that the work needed to add such a feature is hardly worth the convenience. Still, I think it is sad that generators/list comprehensions and for cycles do not share the same syntax. Unfortunately, this example from one of your links convinces that anyway it is too late: (x for x in (l1 if c else l2)) # valid (x for x in l1 if c else l2) # SyntaxError for x in l1 if c else l2 # valid Cheers, Stefano -- http://mail.python.org/mailman/listinfo/python-list
