index between values

[Gribouillis]

Here is a way, using module itertools

>>> import itertools as itt
>>> L = ['visit', 'houston', 'and', 'san', 'antonio', 'and', 'austin', 'and', 'corpus', 'christi']
>>> [list(g) for k, g in itt.groupby(L, key=lambda word: word=='and') if not k]
[['visit', 'houston'], ['san', 'antonio'], ['austin'], ['corpus', 'christi']]

Avoid using 'list' as a variable name, it is the name of a built-in function.
