index between values

[perfringo]

itertools.groupby is superior solution, but to answer OP-s original question ('What goes here?')

>>> lst = ['visit', 'houston', 'and', 'san', 'antonio', 'and', 'austin', 'and', 'corpus', 'christi']
>>> indexes = [i for i, v in enumerate(lst) if v == 'and'] 
>>> result = []
>>> start = 1
>>> for i in indexes:
...     result.append(lst[start:i])
...     start = i + 1
... else:
...     result.append(lst[start:])
...
>>> print(result)
[['houston'], ['san', 'antonio'], ['austin'], ['corpus', 'christi']]
