1. Use For Loop to Iterate Over a Python List The easiest method to iterate the list in Python programming is by using it with for loop. Below I have created a list calledcoursesand iterated over usingforloop. Using aforloop to iterate over a Python list is a common and straightforward ...
Write a function is_num_str_list() that expects a parameter main_list (a list). The function checks ifeachelement of the list is astringwith a proper integer or float by calling the helper function is_num() (see 6.21 LAB). The function...
Finally, you can use the forEach() function that performs the given action on each list element.1 2 3 4 5 fun main() { val list: List<String> = listOf("One", "Two", "Three") list.forEach { println(it) } }Download CodeThat’s all about iterating over a list in Kotlin....
Learn different techniques to iterate over a Java Collection (List, Set and Map) using for-loop, enhanced for-loop, Iterator and Java Stream.
In this tutorial, we will learn some of the ways to iterate over elements of a Dart List. Using for loop and index, you can start at the first element and end at the last element, incrementing the index from 0 to the length of the list. ...

If you want to challenge yourself, there are other ways of looping over arrays other than for and while loops. There are forEach, for-of, and map loops. Try rewriting your array loop by using one of these techniques.Next unit:...
In the following example, we will take a List of Lists and iterate over the elements of the inner lists, using for loop. Main.kt </> Copy fun main(args: Array<String>) { val listOfLists = listOf( listOf(1, 3, 9), listOf("Abc", "Xyz", "Pqr") ...
The Scalafor comprehensionis not specific to lists, but is an extremely powerful way to operate on aListand other sequences. Here's a simple example of how to iterate over a sequence using theforcomprehension (also known as a “forloop”): ...
You may be working with a list type structure that you need to iterate over. Or, you have a general need to repeat an operation until a certain condition is met. In theses scenarios, you can use loops.LoopsA loop iterates over a range of values. For each value, the code does ...
