Sasha walked along the highway
Sasha walked along the road
Masha walked along the highway
Masha walked along the road
Sasha ran on the highway
Sasha ran on the road
Masha ran on the highway
Masha ran on the road

Using itertools.product with str.join:
from itertools import product
a = ['Sasha ','walked along ','the highway']
b = ['Masha ','ran on ','the road']
# option 1: list comprehension
res = [''.join(tup) for tup in product(*zip(a, b))]
# option 2: map
res = list(map(''.join, product(*zip(a, b))))
['Sasha walked along the highway',
'Sasha walked along the road',
'Sasha ran on the highway',
'Sasha ran on the road',
'Masha walked along the highway',
'Masha walked along the road',
'Masha ran on the highway',
'Masha ran on the road']
