Split Python list of strings into seperate lists based on character

Question

I'm trying to figure out how to split the following list into separate lists based on a character in the list.

list = ['@', '2014', '00:03:01', 'Matt', '"login"', '0.01', '@', '2014', '02:06:12', 'Mary', '"login"', '0.01']

I want to create a list after every "@" symbol is introduced. For example, I would want the output to be the following:

NewList1 = ['@', '2014', '00:03:01', 'Matt', '"login"', '0.01'] 

NewList2 = ['@', '2014', '02:06:12', 'Mary', '"login"', '0.01']

Is this possible?

Answer 1

You could use itertools.groupby:

import itertools as IT
import operator

seq = ['@', '2014', '00:03:01', 'Matt', '"login"', '0.01', '@', '2014', '02:06:12', 'Mary', '"login"', '0.01']

groups = (list(g) for k,g in IT.groupby(seq, lambda item: item=='@'))
print(list(IT.starmap(operator.add, IT.izip(*[groups]*2))))

prints

[['@', '2014', '00:03:01', 'Matt', '"login"', '0.01'], ['@', '2014', '02:06:12', 'Mary', '"login"', '0.01']]
