if y in x:
i = x.index(y)
j = i+1
return [i]+[z+j for z in indices(x[j:],y)]
z = [-1] + indices(x,y) + [len(x)]
return [x[z[i]+1:z[i+1]] for i in range(len(z)-1)]

string.split() is very useful, but what if I want to split a list of integers on
some element value?
>> l = [1,2,3,-1,4,5,-1,8,9]
Here's my hideous first pass :
>> [[int(z) for z in x.split(',') if z] for x in ','.join([str(a) for a in
>> [[1, 2, 3], [4, 5], [8, 9]]
When I see code like that I just know I've missed something obvious....
