Here's a way:
>>> a = [1,2,3,4]
>>> b = [5,6,7,8]
>>> [x for S in zip(a, b) for x in S]
[1, 5, 2, 6, 3, 7, 4, 8]

In the same way as above.

Here's one way:
def interleave(*args):
for n in range(min(len(i) for i in args)) :
for i in args:
yield i[n]
HTH,
>>> def xl(a):
... return list(reduce(lambda x,y:x+y,zip(*a)))
...
>>> xl([[1,2],[3,4]])
[1, 3, 2, 4]
like this?

don't know if there's a better way, but
from itertools import izip
def interleave(*doodahs):
for together in izip(*doodahs):
for single in together:
