Python Program to Print Square Numbers Using While Loop

In this tutorial, we are going to discuss how to print all square numbers up to a given number in Python by using a while loop.

As we know in mathematics square numbers have a great concept.

In mathematics, square numbers are numbers that can be represented in the form of the product of an integer by itself.

Simple Code:

n = int(input("Enter the value of n: "))
i = 1
while i*i <= n:
    print(i*i, end=" ")
    i += 1

Output:

Enter the value of n: 20
1 4 9 16 

Code with comments:

# take input from user for the value of n
n = int(input("Enter the value of n: "))

# initialize i to 1
i = 1

# use a while loop to generate square numbers up to n
while i*i <= n:
    # print the current square number
    print(i*i, end=" ")
    # increment i by 1
    i += 1

Explanation:

We first take input from the user for the value of n, up to which we want to generate square numbers.

We initialize i to 1.

Then, we use a while loop to generate square numbers up to n.

In each iteration of the loop, we check if i*i is less than or equal to n.

If it is, we print i*i, which is the current square number.

We also increment i by 1 in each iteration of the loop.
