Why is my index out of range in Python?
String index out of range means that the index you are trying to access does not exist. In a string, that means you’re trying to get a character from the string at a given point. If that given point does not exist, it will try to get a character that is not within the string.

How to get the index of a list?
An easy solution is to transform the list into a dict. You can then use dict.get – you can even set another default value other than None, using the second argument to dict.get. For example, use table.get(i, ‘unknown’) to return ‘unknown’ if the index is out of range. Note that this method does not work with negative indices.
What is the last element in the range in Python?
Because the range (5) is essentially 0 1 2 3 4, so when the loop reaches 4, it will try to get the item to [5]. Since indexing in Python starts with 0 and your list contains 5 elements, the last element would have index 4, so getting a [5] it would mean getting the sixth element which doesn’t exist.
