![]() ![]() ![]() ![]() ![]() In Kotlin, listOf() is used to create a list and we can pass different data types at the same time. val list listOf('A', 'B', 'C') val indexed list.withIndex() println(list) // A, B, C println(indexed.toList()). You can traverse through collection (list, map, set) using the for loop. There is no need to use a traditional for loop in Kotlin, because you can using Kotlin lambdas to makes your code more expressive and readable. withIndex to convert List to IndexedValue iterable (iterator with index). In this tutorial, we will go through example Python programs, that demonstrate how to iterate a list using while loop in Python. Python Program list1 4, 52, 6, 9, 21 index 0 while index < len(list1) : print(list1 index) index + 1 Output 4 52 6 9 21 2. To iterate over elements of a Python List using While Loop statement, start with index of zero and increment the index till the last element of the list using length of the list. It allocates temporary memory for index iterations which makes the overall system to redundant its performance in terms of memory allocation. In Java, when accessing the element from a 2D array using arrfirstsecond, the first index can be thought of as the desired row, and the second index is. Iterate Python List using While Loop In this example, we will take a Python List, and iterate over all the elements of this list using while loop. Kotlin for loop is equivalent to the foreach loop in languages like C. The foreach loop though iterates over an array of elements, the execution is simplified and finishes the loop in less time comparatively. Iterate through collection using for loopĪ collection usually contains a number of objects of the same type and these objects in the collection are called elements or items. Sometimes, one may need (or want) a loop which its iterator (the index variable) is modified within the loop body in addition to the normal incrementation. It iterates through arrays, ranges, collections, or anything that provides for iterate. The syntax of for loop in Kotlin is: for (item in collection) ")*/ ![]()
