python - How to obtain the last index of a list? - Stack Overflow

Index -1 shows you the last index or first index of the end. But if you want to get only the last index, you can obtain it with this function: return len(input_list) - 1. In this case, the input is the list, and the output will be an integer which is the last index number. Did you mean len(list1)-1?

Python List Index: Find First, Last or All Occurrences - datagy

In this tutorial, you’ll learn how to use the Python list index method to find the index (or indices) of an item in a list. The method replicates the behavior of the indexOf () method in many other languages, such as JavaScript. Being able to work with Python lists is an important skill for a Pythonista of any skill level.

Finding first and last index of some value in a list in Python

Perhaps the two most efficient ways to find the last index: lst.reverse() i = lst.index(value) lst.reverse() return len(lst) - i - 1. return len(lst) - operator.indexOf(reversed(lst), value) - 1. Both take only O (1) extra space and the two in-place reversals of the first solution are much faster than creating a reverse copy.

python - Get array elements from index to end - Stack Overflow

Now, i want to access the elements from index 4 to the end: [5], [6], [7], [8]]) When i do this, the resulting vector is missing the last element, now there are five elements instead of six, why does it happen, and how can i get the last element without appending it? Expected output: [5], [6], [7], [8], [9]]) The [:-1] removes the last element.
