-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.
