                 Sometimes, you need to repeat a task multiple times or you may need to repeat the task either a
                 certain number of times or until a condition is satisfied. In Python, the statements that are used to
                 repeat a set of instructions are called iterative or looping statements. Looping statements are very
                 useful and necessary for developing applications.
                 Python provides two types of looping statements—for and while. The for statement is used to repeat
                 an instruction or a set of instructions a fixed number of times. Whereas, the while statement is used to
                 repeat a set of instructions until a condition evaluates to true. Let’s discuss these statements in brief.


                        THE FOR STATEMENT


                 The for loop is a type of iterative statement that allows the user to repeat a set of statements multiple
                 times until a given condition is falsified. The for loop is commonly used when the number of iterations
                 is known in advance or when iterating over a sequence, such as a list, string, tuple, or a range.

                 The syntax of for loop is as follows:
                 for <counter variable> in range(start, stop,
                 step_size):
                        statements
