**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.

- Python decimal Module with Examples
- Python Program to Print all Perfect Squares from a List using List Comprehension and Math Module
- Python Program to Check a Number is Prime or Not

**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

Here we printed the nonperfect square numbers.
