# a quickie: range - x

 P: n/a I want an iterable from 0 to N except for element m (<=M). I could write x = range(N) x.remove(m) but I want it in one expression. Thanks, Ross Nov 30 '06 #1

Because the world will end if you can't? What's wrong with the solution you already have? If you need to use it many times, make it a function. Calling the function is always a one-liner. Here's another solution: x = [i for i in range(N) if i != m] Here's another: x = range(m-1) + range(m+1, N) Here's a generator to do it: def range_except(N, m): """Iterator that returns ints from 0 through N-1 except for m.""" for i in xrange(N): if i != m: yield i -- Steven.
