How do you invert a number in python?
Example 1: Reverse a Number using a while loopOutput Show
4321 In this program, while loop is used to reverse a number as given in the following steps:
Example 2: Using String slicingOutput 654321 Using the string slicing concept, you can get reverse the string. Published on Sep 24,2019 64.4K Views 7 / 11 Blog from Python Programs Python is an interpreted, high-level, general-purpose programming language with different applications. To learn the fundamental concepts of Python, there are some standard programs which would give you a brief understanding of all the concepts practically. Reverse a number in Python is one of these programs which gives the learner a deep understanding of loops and arithmetic operators. This blog will help you understand and implement the ways to reverse a number. It will cover the following topics –
How to reverse a number in Python?It’s simple! You can write a Python program which takes input number and reverse the same. The value of an integer is stored in a variable which is checked using a condition and then each digit of the number is stored in another variable, which will print the reversed number. Numbers can be reversed in Python using different methods, let us take a look at the Python program to implement the same. Python program to reverse a numberThere are two ways to reverse a number in Python programming language –
Reverse a Number using Loop # Get the number from user manually
num = int(input("Enter your favourite number: "))
# Initiate value to null
test_num = 0
# Check using while loop
while(num>0):
#Logic
remainder = num % 10
test_num = (test_num * 10) + remainder
num = num//10
# Display the result
print("The reverse number is : {}".format(test_num))
Output: Program Explanation User value: Number = 123456 and Reverse = 0 First Iteration Second Iteration Third Iteration Fourth Iteration Fifth iteration Sixth iteration Reverse a Number using Recursion
# Python Program to Reverse a Number using Recursion
Num = int(input("Please Enter any Number: "))
Result = 0
def Result_Int(Num):
global Result
if(Num > 0):
Reminder = Num %10
Result = (Result *10) + Reminder
Result_Int(Num //10)
return Result
Result = Result_Int(Num)
print("n Reverse of entered number is = %d" %Result)

We use the python reversed() function to reverse a number by this method. This function returns a pointer that can iterate the string/list in reverse order. We use the join() method of python to obtain the reversed number from this iterator finally.
How do you print reverse digits in Python?Reverse Number In Python. # Python Program to Reverse a Number using While loop.. Number = int(input("Please Enter any Number: ")). Reverse = 0.. while(Number > 0):. Reminder = Number %10.. Reverse = (Reverse *10) + Reminder.. Number = Number //10.. print("\n Reverse of entered number is = %d" %Reverse). How do you reverse a number in Python without loops?Reverse a Number Without using Loop in Python
We read a number and reverse a number using slice operations. We will convert the integer number to string using str() and then, calculate the reverse of a number using the slicing operation. Finally, the result will be displayed on the screen.
How do you reverse input a number?Let's see a simple c example to reverse a given number.. #include int main(). int n, reverse=0, rem;. printf("Enter a number: ");. scanf("%d", &n);. while(n!=0). |
