What does [:-1] mean/do in python? - Stack Overflow

Sometimes -1 is used to express the end of an array of things. My guess is this means to read from beginning to the end of the line (but just a guess, hence not an official answer). I'm not sure it's a dup, because of that "in the context of…" part—which is the part that you and, especially, Pavel Anossov answered.

1] in Python with Examples - Guru99

Whenever a programmer defines [::-1], it suggests that the program has to traverse from start to end in a given list. You can do indexing in python, which helps to slice and dice an iterable sequence such as a list or string. What is [::-1] in Python? What is the type of 1 in Python? How to perform Indexing in Python?

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

Here's an example array in Python: We created an array of integer values from 1 to 5 here. We also accessed the second value by using square brackets and its index in the order, which is 1. Let's say you want to slice a portion of this array and assign the slice to another variable. You can do it using colons and square brackets.

Python Operators - W3Schools

Operators are used to perform operations on variables and values. In the example below, we use the + operator to add together two values: Python divides the operators in the following groups: Arithmetic operators are used with numeric values to perform common mathematical operations: Assignment operators are used to assign values to variables:

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

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 element) holds position “zero”, then After the first element, the second, third and fourth place.

What does the percentage sign mean in Python [duplicate]

What does if n % x actually say? The % does two things, depending on its arguments. In this case, it acts as the modulo operator, meaning when its arguments are numbers, it divides the first by the second and returns the remainder. 34 % 10 == 4 since 34 divided by 10 is three, with a remainder of four.

What Does 'do' Do in Python - Online Tutorials Library

Slicing in Python gets a sub-string from a string. The slicing range is set as parameters i.e. start, stop and step. For slicing, the 1st index is 0. For negative indexing, to display the 1st element to last element in steps of 1 in reverse order, we use the [::-1]. The [::-1] reverses the order. In a similar way, we can slice strings like this.

Python List Slicing - GeeksforGeeks

Python list slicing is fundamental concept that let us easily access specific elements in a list. In this article, we’ll learn the syntax and how to use both positive and negative indexing for slicing with examples. Example: Get the items from a list starting at position 1 and ending at position 4 (exclusive). Parameters:

Python Increment by 1: A Guide to Simple Counting in Code

Python does not have built-in increment or decrement operators (++ and --). The most common way to increment a variable by 1 is using the assignment operator (+=). The addition operator (+) can also be used, but it creates a new object and reassigns it to the variable. Functions like operator.add offer alternative ways, but are less commonly used.

But to explicitly write into the same memory you could use i[:] = i+1 (but it's generally better to use += or the out -argument of several ufuncs).
