Python split for lists

Question

If we have a list of strings in python and want to create sublists based on some special string how should we do?

For instance

Answer 1

reduce comes to mind:

def split(iterable, where):
    def splitter(acc, item, where=where):
        if item == where:
            acc.append([])
        else:
            acc[-1].append(item)
        return acc
    return reduce(splitter, iterable, [[]])


data = ["data","more data","","data 2","more data 2","danger","","date3","lll"]
print split(data, '')

Result:

[['data', 'more data'], ['data 2', 'more data 2', 'danger'], ['date3', 'lll']]
