Iterative Statement
Iterative statement or looping statement refers to those statements which are used to repeat a set of statements
for the specified number of times a until a certain condition is fulfilled. As soon as the condition becomes false,
the loop terminates. These statements consist of three values:
u A starting value(i.e. initializing the starting value of a variable)

u A test expression
u A step value(using increment or decrement operator)
In Python, the two basic types of iterative statements are as follows:

u for loop
u while loop

For Loop

The For loop statement is used to repeat itself over a range of values or sequences when the number of iterations
is known.

In other words, this loop is used when you are sure about how many times a block of code will be executed. The
For loop is also known as definite loop. The basic syntax of for loop is as follows:
for<variable>in<sequence>:
Body of loop(Set of Statements)
Or
for<variable> in range( starting value, final value, step value)
Body of loop(Set of Statements)
You should remember that the initialisation statement is executed only once.
Program to print all the numbers defined in the sequence using for loop.
