What are loop control elements for a while loop in python?

Answer:

The elements of a loop that control and govern its execution are called loop control elements.  These are four in number namely:  

• Initialization expression - It gives an initial value  to the loop variable. This is done outside the loop. 
• Test expression - decides whether the loop is to be executed or not.  
• Body of the loop - consists of the statements  that are executed iteratively till the test  expression remains true.  
• Update expression -  is a statement that  changes the value of the loop variable. This is  given within the body of the loop.
