While Loops in Python A while statement in python sets aside a block of code that is to be executed repeatedly until a condition is falsified. The structure of a while loop allows the total number of iterations, or repetitions, to be unknown from the start. Examples of use cases might be...
A while can also be used along with an else statement. In this as soon as the loops or the iterations get over, the python code will execute the else statement i.e. the code under it. It is important to know that, if there is any error or break inside the else statement then the...
