THE while LOOP
The while loop repeats a block of statements while a given condition is true. The while loop is
commonly used when the number of iterations is not known. In this looping construct, first
the condition is checked, and if it is true, the control will move inside the loop and execute the
statements until the condition becomes false. If the initial condition is false, then the control will
not enter the loop block. The syntax of while loop is as follows:
while(Condition):
statement(s)
increment/decrement
