Ok so this is what I got.. but there is an odd side effect:
def reslice(series):
series.sort()
i = 1
newseries = series[::3]
while(1):
c = series[i::3]
if len(c) >= 3:
newseries = newseries + c
else:
break
i = i + 1
return newseries
a = [2,1,4,3,6,5,8,7,10,9]
b = reslice(a)
print b
>>> [1, 4, 7, 10, 2, 5, 8, 3, 6, 9, 4, 7, 10]
I have one extra 10 that I shouldn't...
