The loop is ended Here, the condition of the while loop is alwaysTrue. However, if the user entersend, the loop termiantes because of thebreakstatement. Pythonwhileloop with anelseclause In Python, awhileloop can have an optionalelseclause - that is executed once the loop condition isFalse...
In Python, a basic while loop looks like this: while[a conditionisTrue]: [do something] The condition we provide to the while statement is the controlling expression, our loop will run until the controlling statement is no longer true. ...
ExampleGet your own Python Server Print i as long as i is less than 6: i =1 whilei <6: print(i) i +=1 Try it Yourself » Note:remember to increment i, or else the loop will continue forever. Thewhileloop requires relevant variables to be ready, in this example we need to def...
If a break statement executes in first program block and terminates the loop then the else clause does not execute. In the following example, while loop calculates the sum of the integers from 0 to 9 and after completing the loop, else statement executes. x = 0; s = 0 while (x < 10...
Python While 2 You’ll notice that this code will run forever, because alive will never be False in this code. Stop the code by making this change, then running it: alive = False Now, this code does nothing at all. Why? Because the while loop will not run if ...

Another common and extended use case ofwhileloops in Python is to createevent loops, which are infinite loops that wait for certain actions known asevents. Once an event happens, the loop dispatches it to the appropriateevent handler. Some classic examples of fields where you’ll find event loo...
The For Loop In Python The for loop in python is used to iterate over a given sequence. The sequence can be a string, a list, a tuple,a set, a dictionary, etc. As long as the length of the sequence is not reached, it will iterate over that sequence. The for loop contains initial...
A while loop is a programming concept that, when it's implemented, executes a piece of code over and over again while a given condition still holds true. The above definition also highlights the three components that you need to construct the while loop in Python: The while keyword; A cond...
