In the previous article, we have discussed Python Program to Convert each Character in a String to an ASCII Value.

**Automorphic Number:**

An automorphic number is one whose square has the same digits as the original number. Examples: 5, 25, 76, and so on.

Example :

let N= 6

N square = 6*6 = 36

The last digit is the same as the given number. Therefore 6 is an automorphic number.

- Python Program to find the nth Kynea Number
- Python Program to Print Series 0, 2, 8, 14, 24, 34 …N

**Examples:**

**Example1:**

**Input:**

Given Number = 625

**Output:**

The given number 625 is an Automorphic Number

**Example2:**

**Input:**

Given Number = 200

**Output:**

The given number 200 is not an Automorphic Number

## Program to Check Automorphic Number or Not

Below are the ways to check the automorphic number or not.

### Method #1: Using pow() function (Static Input)

**Approach:**

- Give the number as static input and store it in a variable.
- Covert the given number into a string using the str() function and find the length of the given number using the len() function.
- Store it in another variable.
- Calculate the square of the given number and store it in a variable.
- Get the last n digits of the square number using modulus and pow() functions and store it in another variable.
- Check if the last n digits are equal to the given input number using the if conditional statement.
- If the statement is true, then print “The given number is an Automorphic Number”.
- Else print “The given number is not an Automorphic Number”.
- The Exit of the Program.

**Below is the implementation:**

# Give the number as static input and store it in a variable. gvn_numbr = 6 # Covert the given number into a string using the str() function and # find the length of the given number using the len() function. # Store it in another variable. lenth = len(str(gvn_numbr)) # Calculate the square of the given number and store it in a variable. sqr_num = gvn_numbr**2 # Get the last n digits of the square number using modulus and pow() functions and # store it in another variable. lst_n_digits = sqr_num % pow(10, lenth) # Check if the last n digits are equal to the given input number using the if # conditional statement. if lst_n_digits == gvn_numbr: # If the statement is true, then print "The given number is an Automorphic Number". print("The given number", gvn_numbr, "is an Automorphic Number") else: # Else print "The given number is not an Automorphic Number". print("The given number", gvn_numbr, "is not an Automorphic Number")

**Output:**

The given number 6 is an Automorphic Number

### Method #2: Using pow() function (User Input)

**Approach:**

- Give the number as user input using the int(input()) function and store it in a variable.
- Covert the given number into a string using the str() function and find the length of the given number using the len() function.
- Store it in another variable.
- Calculate the square of the given number and store it in a variable.
- Get the last n digits of the square number using modulus and pow() functions and store it in another variable.
- Check if the last n digits are equal to the given input number using the if conditional statement.
- If the statement is true, then print “The given number is an Automorphic Number”.
- Else print “The given number is not an Automorphic Number”.
- The Exit of the Program.

**Below is the implementation:**

# Give the number as user input using the int(input()) function and store it in a variable. gvn_numbr = int(input("Enter some random number = ")) # Covert the given number into a string using the str() function and # find the length of the given number using the len() function. # Store it in another variable. lenth = len(str(gvn_numbr)) # Calculate the square of the given number and store it in a variable. sqr_num = gvn_numbr**2 # Get the last n digits of the square number using modulus and pow() functions and # store it in another variable. lst_n_digits = sqr_num % pow(10, lenth) # Check if the last n digits are equal to the given input number using the if # conditional statement. if lst_n_digits == gvn_numbr: # If the statement is true, then print "The given number is an Automorphic Number". print("The given number", gvn_numbr, "is an Automorphic Number") else: # Else print "The given number is not an Automorphic Number". print("The given number", gvn_numbr, "is not an Automorphic Number")

**Output:**

Enter some random number = 25 The given number 25 is an Automorphic Number
