Feb 26, 2025 · In this example, the Python code reverses a given number using a while loop. It prints both the original and reversed numbers. The example demonstrates reversing the number 6789. Explanation: number n1 is processed by repeatedly extracting its last digit, appending it to rev, and then removing the last digit from n1 using the // operator.

In this program, while loop is used to reverse a number as given in the following steps: First, the remainder of the num divided by 10 is stored in the variable digit. Now, the digit contains the last digit of num, i.e. 4. digit is then added to the variable reversed after multiplying it by 10.

Mar 20, 2025 · The most simple way to reverse a number in Python is to convert it to a string, reverse the string, and convert it back to an integer: """ Reverse a number using string conversion. Args: number: The number to reverse. Returns: The reversed number. """ # Handle negative numbers. if number < 0: return -int(str(-number)[::-1])

Jan 9, 2021 · With for -loop you would have to convert int to str to know how much diggits it has. With for -loop you could eventually use iterator / generator which will raise __StopIter__ at the end of data - but probably this iterator/generator whould have to use while for this :)

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.

We will develop a program to reverse a number in python using for loop. To reverse a number we need to extract the last digit of the number and add that number into a temporary variable with some calculation, then remove the last digit of the number. Do …

Dec 24, 2022 · In this step, we will Initialise an empty string variable called reverse to store the reversed number. Next, we use a for loop to iterate through each digit of the number. The loop iterates over a range starting from the length of the number and going down to 1.

In this tutorial, we are going to learn how to reverse a given number in Python by making the reverse of digits. So let’s get started. To reverse a given number we need to follow some steps. Steps to follow: User has to enter a value. Divide the number with 10 to remove last digit. Print the reverse number.

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 31, 2025 · Learn to reverse a number in Python using different ways such string slicing, a mathematical approach, recursion and using list reversal
