What are the four elements of a while loop in Python?

The four elements of a while loop in Python are:

1. Initialization Expressions — It initializes the loop control variable and it is given outside the while loop before the beginning of the loop.
2. Test Expression — If its truth value is true then the loop-body gets executed otherwise not.
3. The Body of the Loop — It is the set of statements that are executed repeatedly in loop.
4. Update Expressions — It updates the value of loop control variable and it is given inside the while loop.
