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. For example, coun...
With the break statement, you can terminate the execution of a while loop and make your program continue with the first statement immediately after the loop body.Here’s a short script that demonstrates how the break statement works:Python break.py ...

The infinite loop is a special kind of while loop; it never stops running. Its condition always remains True. An example of an infinite loop: while 1==1: print("In the loop") This program would indefinitely print "In the loop". You can stop the program's execution by using the Ctrl...

If you were to make this mistake on your system, you would have to interrupt the Python program by pressing the Control + C keys. Example In the below example, you will create the variableoffsetwith an initial value of8. Then you will write awhileloop that keeps running as long as the...

While Loop The while loop is one of the first loops that you'll probably encounter when you're starting to learn how to program. It is arguably also one of the most intuitive ones to understand: if you think of the name of this loop, you will quickly understand that the word "while"...
