sadly not really. list comprehensions are the same speed as for loops.
newlist = []
for x in oldlist:
newlist.append(abs(x))
results in nearly identical speed with the list comprehension:
newlist = [abs(x) for x in oldlist]
of course, for simple problems like this, the map/filter/reduce family
can run them a bit quicker:
newlist = map(abs, oldlist)
