...n seen or seen_add(x))]
Why assign seen.add to seen_add instead of just calling seen.add? Python is a dynamic language, and resolving seen.add each iteration is more costly than resolving a local variable. seen.add could have changed between iterations, and the runtime isn't smart enough to rule t...

Python: fastest way to create a list of n lists

The probably only way which is marginally faster than
d = [[] for x in xrange(n)]
is
