Python Array Indexing - GeeksforGeeks

Python arrays are zero-indexed, just like Lists. First element is at index 0, the second at index 1 and so on. Let's see how indexing works with arrays using array module: Access Array Element with Index. We can access elements from the beginning of the array using positive indices: Python

python - Negative list index? - Stack Overflow

List indexes of -x mean the xth item from the end of the list, so n[-1] means the last item in the list n.Any good Python tutorial should have told you this. It's an unusual convention that only a few other languages besides Python have adopted, but it is extraordinarily useful; in any other language you'll spend a lot of time writing n[n.length-1] to access the last item of a list.

Python Slicing – How to Slice an Array and What Does [::-1] Mean?

When you specify a start and end index of 1 and 5, respectively, slicing will select values at index 1, index 2 (1 increment to the previous index), index 3 (1 increment to the previous index) and index 4 (and one increment to the previous index). In this slicing, a step of 1 is used by default. But you can provide a different step. Here's how:

Negative Indexing in Python List – How to Use “-1” Parameter

A Python list can have many elements, and refer to a particular element among hundreds of elements present in them, indexing is used. Indexing in Python is a way to refer to individual items by their position within a list. In Python, objects are “zero-indexed”, which means that position counting starts at zero, 5 elements exist in the list, then the first element (i.e. the leftmost ...

Meaning of list [-1] in Python - Stack Overflow

So, if you wanted the last element in array, you would call array[-1]. All your return c.most_common()[-1] statement does is call c.most_common and return the last value in the resulting list, which would give you the least common item in that list. Essentially, this line is equivalent to: temp = c.most_common() return temp[len(temp) - 1]

How to Use Python Array Index -1? - Python Guides

In this tutorial, I will explain how to use the Python array index -1 in detail with examples. In a recent Python webinar, array index -1 was the topic of the discussion. We will use index -1 to fetch the last element of the given collection without knowing the length of the collection. Let us learn more about this topic.

That is: >>> x [0][2] 2. ... In this case, if the index arrays have a matching shape, and there is an index array for each dimension of the array ...
