... and taking Marko's good advice, what I think you really wanted:


 >>> def poplist(L):
	done = False
	while not done:
		yield L[::-1][:1:]
		L = L[::-1][1::][::-1]
		if len(L)==0: done=True

		
 >>> L=[1, 2, 3, 4, 5, 6, 7]

 >>> m=[]

 >>> pop = poplist(L)

 >>> for n in poplist(L):
	m.append(n[0])

 >>> m
[7, 6, 5, 4, 3, 2, 1]
 >>>
