In Python list comprehension is it possible to access the item index?

python list list-comprehension

Consider the following Python code with which I add in a new list2 all the items with indices from 1 to 3 of list1:

for ind, obj in enumerate(list1):
    if 4 > ind > 0:
        list2.append(obj)

How would you write this using list comprehension, if I have no access to the indices through enumerate?

something like:

list2 = [x for x in list1 if 4 > ind > 0]

but since I have no ind number, would this work?

list2 = [x for x in enumerate(list1) if 4 > ind > 0]
