In my use case I would simply have to write;:
[l.strip() as stripped for l in text.split('\n') if stripped != '']
Which seems to me clear and concise.
-1 For me it is backward and confusing, whereas
lines = [] for l in test: l = l.strip() if l: lines.append(l)
is clear as could be.
To me, the drive to replace all for loops with list comps is mis-directed. There is no end to the clauses people could propose to add: while, when, whatever, until, unless. mapped_to, transformed_by, and so on. The result would soon by something quite different from Python as we know it.
Indeed, probably something approaching Common Lisp's overcomplicated "loop" macro: http://www.unixuser.org/~euske/doc/cl/loop.html - Chris ======== Follow the path of the Iguana... Rebertia: http://rebertia.com Blog: http://blog.rebertia.com
