The While loop ends here!
THE INFINITE LOOP
If the condition given in a loop never becomes false, then the loop will never terminate and run
indefinitely. This type of loops is called an infinite loop.
Example:
while(1)
print(“Hello”)
Output: Hello will be printed an infinite number of times.
To come out of the infinite loop, close the interactive mode and restart the idle.
Just as the heart repeatedly pumps
blood, iteration in programming
involves repeatedly running a set
of instructions.
THE JUMP STATEMENTS
Sometimes, there is a situation when the control of the program needs to be transferred out of
the loop body, even if all the values of the iterations of the loop have not been completed. For this
purpose, jump statements are used in Python. Python offers two jump statements—break and
continue, which are used within the loop.
The break Statement
The break is a keyword in Python which is used for sending the program control out of the loop. The
break statement halts the execution of a loop and program flow switches to the statement after the
loop. A single break statement will break out of only one loop. The syntax of the break statement
is as follows:
#loop statement
break
