Splitting a list into uneven groups?

Question

I know how to split a list into even groups, but I\'m having trouble splitting it into uneven groups.

Essentially here is what I have: some list, let\'s call it

Answer 1

This solution keeps track of how many items you've written. It will crash if the sum of the numbers in the second_list is longer than mylist

total = 0
listChunks = []
for j in range(len(second_list)):
    chunk_mylist = mylist[total:total+second_list[j]]
    listChunks.append(chunk_mylist)
    total += second_list[j]

After running this, listChunks is a list containing sublists with the lengths found in second_list.
