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

I'm not sure wether this is the most "pythonic" way of solving it.

def split_seq(seq, sep):
    start = 0
    while start < len(seq):
        try:
           stop = start + seq[start:].index(sep)
           yield seq[start:stop]
           start = stop + 1
        except ValueError:
           yield seq[start:]
           break

ll = ["data","more data","","data 2","more data 2","danger","","date3","lll"]
p = [i for i in split_seq(ll,"")]
