Once the condition evaluates toFalse, the loop terminates. Tip:We should update the variables used inconditioninside the loop so that it eventually evaluates toFalse. Otherwise, the loop keeps running, creating an infinite loop. Flowchart of Python while Loop Flowchart of Python while Loop Example...
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. ...
The while Loop With thewhileloop we can execute a set of statements as long as a condition is 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 »...
Python Syntax whileTrue:ifcondition_1:break...ifcondition_2:break...ifcondition_n:break This syntax works well when you have multiple reasons to end the loop. It’s often cleaner to break out from several different locations rather than try to specify all the termination conditions in the lo...
While loopLoops are used to repeatedly execute a block of program statements. The basic loop structure in Python is while loop. Here is the syntax.Syntax:while (expression) : statement_1 statement_2 ...The while loop runs as long as the expression (condition) evaluates to True and execute...
The While Loop In Python The while loop statement is used to repeat a block of code till a condition is fulfilled. When we don’t know the exact number of times, a loop statement has to be executed. We make use of while loops. This way, till the test expression holds true, the loo...
Python will then go back to the condition of the while loop with the new error equal to 12.5. The condition will again be true, and the code is executed. Python will again move back to the condition of the while loop and attempt to re-run the code. Because 3.125 is greater than 1,...

The code in the body of a while loop is executed repeatedly. This is called iteration. while循环体中的代码被重复执行。这叫做迭代。 The infinite loop is a special kind of while loop; it never stops running. Its condition always remains True. ...
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...
