Dear children! In the previous class, you learnt the basic concepts of Python, such as operators
and conditional statements. Now, you will learn about the iterative statements in detail. In a
program, there are many situations where we need to repeat same set of tasks again and again. 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 :
1. for

2. while

Let’s discuss these constructs in brief.

THE FOR STATEMENT
The for statement executes a simple or compound statement for a fixed number of times. The
syntax of the for statement is given below:

for <variable> in <iterator>:
