python comprehension split list

I have recently finished a master thesis about genetic algorithms for text segmentation via python, so I have a complicated relationship with python. Actually it always helps to me. This post consists of some python especially list and dictionary comprehensions.

First of all, splitting a list regarding with given another list. For example, you have a list which has sentences as elements. Another list is reference splitter and consists of 0s and 1s.

sentences = ["first sentence", "second sentence", "third sentence",
             "fourth sentence", "fifth sentence"] 

reference = [0,0,1,0] 

This list indicates that cut the number of index of '1' at the gap in the sentences list and result list will include two sublists

result = [["first sentence", "second sentence", "third sentence"],
          ["fourth sentence", "fifth sentence"]] 

def split_segments_according_to_reference(reference, sentences):
        temp = []
        result = []
        for i, j in zip(reference,range(len(sentences))):
            temp.append(sentences[j])
            if i == 1:
                result.append(temp)
                temp = []
        if len(sentences) == len(reference)+1:
            temp.append(sentences[-1])
            result.append(temp)
            temp = []
        return result
