sorry if this came up before, but I tried searching the archives and found nothing. It would be really nice if new builtin truth functions in 2.5 took a predicate argument(defaults to bool), so one could write, for example:
seq = [1,2,3,4,5] if any(seq, lambda x: x==5): ... which is clearly more readable than reduce(seq, lambda x,y: x or y==5, False)
How about this?
if any(x==5 for x in seq):- Previous message: [Python-Dev] Any reason that any()/all() do not take a predicate argument?
