Find indexes of sequence in list in python

Question

I am quite new and I hope it\'s not too obvious, but I just can\'t seem to find a short and precise answer to the following problem.

I have two lists:

Answer 1

With a list comprehension:

>>> [(i, i+len(b)) for i in range(len(a)) if a[i:i+len(b)] == b]
[(3, 6)]

Or with a for-loop:

>>> indexes = []
>>> for i in range(len(a)):
...    if a[i:i+len(b)] == b:
...        indexes.append((i, i+len(b)))
... 
>>> indexes
[(3, 6)]
