I'm sure there must have been a past thread about this topic but I don't know how to find it: How about extending the "for <X> in" syntax so that X can include default arguments ? This would be very useful for list/generator comprehensions, for example being able to write something like:
[x*y-z for (x,y,z=0) in (1,2,3), (4,5), (6,7,8)]
instead of the less elegant explicit loop version that has to check for the length of each sequence. What do you think ?
How did you get the data in that format in the first place? It looks a bit strange to me. Wouldn't it be easier to fill in default values when you gather data as opposed to when you use it?
