Python Program to Check Palindrome Number

πŸ™‹ Introduction

In the realm of programming, tasks involving numbers often include checking for special properties. One interesting property is whether a number is a palindrome.

A palindrome number reads the same backward as forward.

In this tutorial, we will explore a Python program designed to check whether a given number is a palindrome.

The program involves reversing the digits of the number and comparing it with the original number.

πŸ“„ Example

Let's delve into the Python code that accomplishes this task.

is_palindrome.py
Copied
Copy To Clipboard
# Function to check if a number is a palindrome
def is_palindrome(number):
    original_number = number
    reversed_number = 0

    # Reverse the digits of the number
    while number != 0:
        remainder = number % 10
        reversed_number = reversed_number * 10 + remainder
        number //= 10

    # If the reversed number is equal to the original number, it is a palindrome
    return original_number == reversed_number

# Driver program
if __name__ == "__main__":
    # Replace this value with the number you want to check
    number = 121

    # Call the function to check if the number is a palindrome
    if is_palindrome(number):
        print(f"{number} is a palindrome number.")
    else:
        print(f"{number} is not a palindrome number.")

πŸ’» Testing the Program

To test the program with different numbers, modify the value of number in the code.

Output
121 is a palindrome number.

Run the script to check if the specified number is a palindrome.

🧠 How the Program Works

  1. The program defines a function is_palindrome that takes a number as input and returns True if the number is a palindrome, and False otherwise.
  2. Inside the if __name__ == "__main__": block, replace the value of number with the desired number you want to check.
  3. The program calls the is_palindrome function and prints the result using print().

πŸ“ Between the Given Range

Let's delve into the python code that checks for palindrome numbers in the range 100 to 200.

is_palindrome.py
Copied
Copy To Clipboard
# Function to check if a number is palindrome
def is_palindrome(number):
    return str(number) == str(number)[::-1]

# Palindrome numbers in the range 100 to 200
palindrome_numbers = [num for num in range(100, 201) if is_palindrome(num)]

# Output the palindrome numbers
print("Palindrome Numbers in the Range 100 to 200:")
print(" ".join(map(str, palindrome_numbers)))

πŸ’» Testing the Program

Output
Palindrome Numbers in the range 100 to 200:
101 111 121 131 141 151 161 171 181 191

Simply run the Python script to see the palindrome numbers in the range of 100 to 200.

🧠 How the Program Works

  1. The program defines a function is_palindrome that checks if a given number is a palindrome by comparing it to its reversed version.
  2. It then generates a list of palindrome numbers within the range of 100 to 200 using list comprehension.
  3. The program outputs the palindrome numbers in the specified format.

🧐 Understanding the Concept of Odd Number

Before delving into the code, let's understand the concept of palindrome numbers. A palindrome number reads the same backward as forward.

For example, 121 is a palindrome number.

🎒 Optimizing the Program

While the provided program is effective, consider exploring and implementing alternative approaches or optimizations for checking palindrome numbers.

Feel free to incorporate and modify this code as needed for your specific use case. Happy coding!
