Usage of the while Loop

The while loop can be used in three situations:

• Repeating a set of statements until a condition remains True.
• Repeating a set of statements a finite number of times.
• Iterating through a string, list, and tuple.

First usage of the while loop

When we use the while loop to repeat a set of statements until a condition remains True, it means that we don’t know beforehand how many times the statements need to be executed.
