Using Iterable in for loop

Essential Java

Classes implementing Iterable< interface can be used in for loops. This is actually only syntactic sugar for getting an iterator from the object and using it to get all elements sequentially; it makes...

Iterators

Codecademy

Iterators are used to do one thing multiple times. They are used in tandem with collections (Hashes, Arrays, etc…). A collection is an object that stores a group of data members. Each Iterator Returns...

Iterators

Codecademy

Iterators are used to loop over a group of data members, or a collection. An iterator is an object that implements the iteration protocols. Many built-in data types ( strings , arrays , maps , sets , ...

Using the raw iterator

Essential Java

While using the foreach loop (or “extended for loop”) is simple, it’s sometimes beneficial to use the iterator directly. For example, if you want to output a bunch of comma-separated values, but don’t...

Iterator

Codecademy

An iterator is an object that allows code to step through collections. Java has Iterator and ListIterator objects, both imported through the java.util package. The main difference between the two is t...

The Python Standard Library

itertools — Functions creating iterators for efficient looping This module implements a number of iterator building blocks inspired by constructs from APL, Haskell, and SML. Each has been recast in a...

Iterators

Codecademy

Iterators are used to loop through a collection of data. They are also used to repeat processes a preset or infinite amount of times. Iteration Types In Lua, there are multiple ways to iterate through...

Working With Python's Iterators, Iterables, and Iteration

Real Python

This is a preview of the video course, "Efficient Iterations With Python Iterators and Iterables." Python’s iterators and iterables are two different but related tools that come in handy when you need...

Iterators

Codecademy

In Python, an iterator is an object representing a collection of elements (such as data or methods) where each element can be accessed by traversing through the collection to perform the required task...

Iterators & Iterables in Python

Towards Data Science

In this post, we will discuss python iterators and iterables. We will go over the definitions of each of these objects as well as work towards developing an understanding of the underlying concepts…

Iterable vs Iterator — Python

Analytics Vidhya

We all scan items for various purpose. In computing too we scan collection of items. Iterable and Iterator are concepts with scanning. I am glad to have come across this concept and would like to…

Iterables and Iterators in Python

Towards Data Science

In this article, we will learn the differences between iteration, iterables, and iterators, how to identify iterables and iterators, and why it can be useful to be able to do so. Broadly speaking, an…...

Iterators

Codecademy

An iterator repeatedly executes a code block a number of times. This number may be determined or indefinite. In the latter case, an iterator will endlessly execute a code block until some external eve...

Efficient Iterations With Python Iterators and Iterables

Real Python

In this video course, you'll learn what iterators and iterables are in Python. You'll learn how they differ and when to use them in your code. You'll also learn how to create your own iterators and it...

Iterables

Javascript.info

Iterable objects are a generalization of arrays. That’s a concept that allows us to make any object useable in a for..of loop. Of course, Arrays are iterable. But there are many other built-in objects...

Advanced Iterators

Dive into Python 3

Just as regular expressions put strings on steroids, the itertools module puts iterators on steroids. But first, I want to show you a classic puzzle. Puzzles like this are called cryptarithms or alpha...

For Loops

Towards Data Science

For loops are what allow us to iterate over collections like lists, tuples, sets, and dictionaries in Python. While you can choose to manipulate each item in individual lines of code, this would be…

Python Iterators and Iterables.

Analytics Vidhya

For loops and Comprehensions are used to iterate over a source(List, Dictionary or a Set), picking items one by one and performing some actions on it. But sometimes more fine-grained control is…

Creating your own Iterable structure for use with Iterator or for-each loop.

Essential Java

To ensure that our collection can be iterated using iterator or for-each loop, we have to take care of following steps: The stuff we want to iterate upon has to be Iterable and expose iterator() . Des...

For Loops

Essential Java

for (int i = 0; i < 100; i++) { System.out.println(i); } The three components of the for loop (separated by ; ) are variable declaration/initialization (here int i = 0 ), the condition (here i < 100 )...
