Python: split a list based on a condition?

Question

What\'s the best way, both aesthetically and from a performance perspective, to split a list of items into multiple lists based on a conditional? The equivalent of:

Answer 1

images = [f for f in files if f[2].lower() in IMAGE_TYPES]
anims  = [f for f in files if f not in images]

Nice when the condition is longer, such as in your example. The reader doesn't have to figure out the negative condition and whether it captures all other cases.
