What is a While Loop ?
                  A while loop in Python is used to execute a block of code repeatedly as long as a given condition remains True. 

Syntax :
Python 
while condition: statement(s)

Example :
Python
i = 1 while i <= 5: print(i) i += 1 #output 1 2 3 4 5

Infinite While Loop :
Python 
i = 1 while i <= 5: print(i)

This creates an infinite loop because i never increments.


Using Else in While Loop :

Python 
i = 1 while i <= 3: print(i) i += 1 else: print("Loop completed") #output 1 2 3 Loop completed
