Feb 26, 2025 · In this article, we will explore various techniques for reversing a number in Python. Using String Slicing. In this example, the Python code reverses a given number by converting it to a string, slicing it in reverse order and then converting it back to an integer.

Mar 19, 2025 · # Python 3 program to reverse a number def reversDigits (n): # converting number to string s = str (n) # reversing the string s = s [::-1] # converting string to integer n = int (s) # returning integer return n if __name__ == "__main__": n = 4562 print (reversDigits (n))

Mar 20, 2025 · Learn how to reverse a number in Python using loops, recursion, and string manipulation. Explore different methods to efficiently reverse digits in Python.

One way to reverse a number is by using arithmetic operations. We can extract the last digit of the number using the modulo operator and build the reversed number by multiplying it with 10 and adding the next digit. Here’s a Python program that implements this approach. reversed_num = 0. while number > 0: last_digit = number % 10.

Oct 23, 2021 · Python makes it easy to reverse a number by using a while loop. We can use a Python while loop with the help of both floor division and the modulus % operator. Let’s take a look at an example to see how this works and then dive into why this works: digit = number % 10 . reversed_number = reversed_number * 10 + digit.

The following is a Python program to reverse the digits of a number. Sample Run 1: Sample Run 2: Try it out: To reverse the digits of a number literally, here is the algorithm: Extract the rightmost digit of the number being reversed.

In this tutorial, we will learn different ways to reverse a number in Python. The first approach is to convert number to string, reverse the string using slicing, and then convert string back to number. The second approach is to use while loop to pop the last digit in the loop, and create a new number with popped digits appended to it. 1.

Mar 7, 2024 · Reversing a number by converting it to a string is the most straightforward method. Simply convert the integer to a string with str(), and then apply slicing with [::-1] to reverse it. Lastly, convert it back to an integer using int(). Here’s an example: Output:

Given an integer input the objective is to reverse the given integer number using loops and slicing. Therefore, we’ll write a program to Find the Reverse of a Number in Python Language. We need to write a python code to reverse the given integer and print the integer.

Apr 8, 2025 · Explanation. 1. Initialize the variables. number holds the value you want to check (in this case, 12321).; original_number is a copy of the number so you can compare it later after reversing it.; reversed_number starts at 0 and will be used to build the reversed version of the number.; 2. Use while loop to reverse the digits of the number. Extract the last digit using the modulus operation ...
