This much I knew, but _why_ and _when_ would I choose to use list comprehension (for good Python style), rather than using a simple "traditional" loop ? If I want to generate something that's simply ( [1] + [2] + [3]+... ) then list comprehension is obviously the tool of choice. I suspect though that there's more to it than this. Is list comprehension also treatable as a sneaky concise formulation for nested lists, where they're as much about selection of individual elements, so much as concatenation of the sequence? What happens if a comprehension has side effects, such as from calling a function within it? Is this regarded as good or bad coding style? Is it evil (as structured programming would claim) or is it a concise formulation for an iterator or visitor pattern ? -- http://mail.python.org/mailman/listinfo/python-list
