There are two errors in the code:

1. The append() method should be called on the list s, not on its own.
2. After appending [5,6] to s, the new list will have three elements, so attempting to access s[2] will result in an IndexError.

Here is the corrected code:

s = [1, 2]
s.append([5, 6])
print(s[2])  # prints [5, 6]

Note that s[2] returns the entire list [5, 6], not just the element 5. If you want to access the element 5, you can do so by indexing into the inner list: s[2][0] would return 5
