Tuple slicing not returning a new object as opposed to list slicing

Question

In Python (2 and 3). Whenever we use list slicing it returns a new object, e.g.:

l1 = [1,2,3,4]
print(id(l1))
l2 = l1[:]
print(id(l2))

Output

Answer 1

Not sure about this but it seems that Python provides you with a new pointer to the same object to avoid copying since the tuples are identical (and since the object is a tuple, it's immutable).
