Python while Loop Statements

While loop is used in Python to repeat a block of code until the condition in while statement is true. It is also used quite frequently in Python.

The syntax of while in python is given below.

i=1;  
while i<=5:  
    print(i);  
    i=i+1;

while loop with else

We can use an optional block with a while loop that will execute once the loop is terminated. But one thing to notice is that, if the loop contains any loop control statement ( i.e. break, continue or pass ), then the else block is not executed.

i = 1
while i<=5:  
    print(i)
    i = i + 1
else:
    print("Loop terminated")
