hello, I generate dynamically a sequence of values, but this "sequence" could also have length 1 or even length 0.
So I get some line in the form of: line = '(2,3,4)' line = '' line = '(2)' (in fact these are not constant numbers, but all kind of integer variables, coming from all over the program, selected from a tree, that shows all "reachable" variables) So in fact I get the value from an exec statement, like this exec 'signals = ' + line Now I want to iterate over "signals", which works perfect if there are 2 or more signals, but it fails when I have none or just 1 signal. for value in signals : do something As this meant for real-time signals, I want it fast, so (I think) I can't afford extensive testing. Any smart solution there ? thanks, Stef Mientki -- http://mail.python.org/mailman/listinfo/python-list
