In Python (and many programming languages), list indices are zero-based. This means that for a list of four elements like [a, b, c, d]
, the indices are as follows:
- Index 0: a
- Index 1: b
- Index 2: c
- Index 3: d
Since there is no index 4 in a list of four elements, the correct response is:
There exists no element at index 4.
