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…
