In this section, we will see how loops work in python. Looping is simply a functionality that is commonly used in programming for achieving repetitive tasks. It can vary from iterating each element of an array o
In Condition controlled Loops, there is condition(expression) that controls the loop. In python there is 1 loop falls under this category. 1. Python while Loop Python while loop is used to repeat a block of code as long as the given condition stays true. Here’s an example: a=1whilea<...
The Python while statement continues to execute a block of code as long as a test condition is true. The loop stops running when the condition no longer holds. Therefore, it is impossible to tell in advance how many times the loop might run. To determine whether the loop should iterate ag...
For Loops in Python For Loops in Python (Definite Iteration)Darren Jones04:27 Mark as Completed Supporting Material Recommended TutorialAsk a Question This lesson goes into the guts of the Pythonforloop and shows you how iterators work. You’ll learn how to create your own iterators and get ...
Let us go through the loop control statements briefly. Iterator and Generator Iteratoris an object which allows a programmer to traverse through all the elements of a collection, regardless of its specific implementation. In Python, an iterator object implements two methods,iter()andnext(). ...
In this quiz, you'll test your understanding of Python's for loop. You'll revisit how to iterate over items in a data collection, how to use range() for a predefined number of iterations, and how to use enumerate() for index-based iteration.

This tutorial explains the role of Loops in Python, their types: For, While, Nested Loops with syntax and practical programming examples.
Many objects in Python are iterable which means we can iterate over the elements of the object. Such as every element of a list or every cha
Python comes with two inbuilt keywords to interrupt loop iteration,breakandcontinue. Break Keyword In While loop The break keyword immediately terminates the while loop. Let's add a break statement to our existing code, x =1while(x<=3):print(x) x = x +1ifx ==3:breakelse:print("x is...
