# Square numbers in python – Python Program to Print Non Square Numbers

Square numbers in python: In the previous article, we have discussed Python Program to Remove any Non-ASCII Characters
Non-square numbers :

How to square numbers in python: Non-square numbers are those that are not perfect squares of any number. When you multiply any number by itself, you get a square number. A non-square number is the inverse of the same. For example, 16 is a square number because it can be written as 4 x 4, whereas 7 is not. Other non-square numbers include 2, 3, 5, 6, 7, 8, and 10.

math module :

The math module is a standard Python module that provides access to various mathematical functions for performing mathematical operations.

The math module in Python provides access to the following mathematical functions: exp(x), pow(x,y), log10(x), sqrt(x), and so on.

Examples:

Example1:

Input:

Given range = 8

Output:

The non square numbers in a given range =
2
3
5
6
7

Example 2:

Input:

Given range = 15

Output:

The non square numbers in a given range =
2
3
5
6
7
8
10
11
12
13
14

## Program to Print Non-Square Numbers

Below are the ways to print the non-square numbers.

### Method #1: Using math Module (Static input)

Approach:

• Import math module using the import keyword.
• Give the range as static input and store it in a variable.
• Loop from 0 to given number using for loop.
• Calculate the square root of the iterator value using math.sqrt() function and store it in another variable “sqr_rt”.
• Check if the above obtained  “sqr_rt” multiplied with itself is equal to the iterator value using the if conditional statement.
• If the statement is true, then increase the value of the iterator by ‘1’.
• Else print the iterator value.
• The Exit of the program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the range as static input and store it in a variable.
gvn_num = 15
# Loop from 0 to given number using for loop.
print("The non square numbers in a given range = ")
for itr in range(0, gvn_num):
# Calculate the square root of the iterator value using math.sqrt() function and
# store it in another variable "sqr_rt".
sqr_rt = int(math.sqrt(itr))
# Check if the above obtained  "sqr_rt" multiplied with itself is equal to the iterator
# value using the if conditional statement.
if itr == sqr_rt*sqr_rt:
# If the statement is true, then increase the value of the iterator by '1'.
itr = itr + 1
# Else print the iterator value.
else:
print(itr)


Output:

The non square numbers in a given range =
2
3
5
6
7
8
10
11
12
13
14

### Method #2: Using math Module (User input)

Approach:

• Import math module using the import keyword.
• Give the range as user input using the int(input()) function and store it in a variable.
• Loop from 0 to given number using for loop.
• Calculate the square root of the iterator value using math.sqrt() function and store it in another variable “sqr_rt”.
• Check if the above obtained  “sqr_rt” multiplied with itself is equal to the iterator value using the if conditional statement.
• If the statement is true, then increase the value of the iterator by ‘1’.
• Else print the iterator value.
• The Exit of the program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the range as user input using the int(input()) function and store it in a variable.
gvn_num = int(input("Enter some random number = "))
# Loop from 0 to given number using for loop.
print("The non square numbers in a given range = ")
for itr in range(0, gvn_num):
# Calculate the square root of the iterator value using math.sqrt() function and
# store it in another variable "sqr_rt".
sqr_rt = int(math.sqrt(itr))
# Check if the above obtained  "sqr_rt" multiplied with itself is equal to the iterator
# value using the if conditional statement.
if itr == sqr_rt*sqr_rt:
# If the statement is true, then increase the value of the iterator by '1'.
itr = itr + 1
# Else print the iterator value.
else:
print(itr)


Output:

Enter some random number = 8
The non square numbers in a given range =
2
3
5
6
7
