[Tutor] comparing two numpy arrays

[Andy Cheesman]

Thats a great solution, thanks! I've googled a bit for manipulation of
sets into other data structure(lists, arrays) and not seen much. Is the
only way of interconversion a brute force method?

i.e	a = set([1, 2, 3])
	b = []
	for thing in a:
		b.append(thing)
