How to Create Reverse a Number in Python
In this tutorial, we will create a "How to Reverse a Number in Python". We will explore the basics of creating a program to reverse a number. The objective of this tutorial is to learn new concepts related to the Python programming language. I will provide a sample program to demonstrate the coding process for this tutorial.
This topic is simple and easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program I will show you is how to reverse a provided number. I will do my best to provide you with the easiest method of creating this program, called "Reverse a Number". So, let's get started with the coding.
Getting Started:
First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.
Creating Main Function
This is the main function of the application. The following code will display a simple GUI in terminal console of reverse a number. To do this, simply copy and paste these blocks of code into the IDLE text editor.- while True:
- print("\n\n================ Reverse Number Program ================\n\n")
- ret=False
- num = int(input("Enter a number: "))
- reversed_num = 0
- while num != 0:
- digit = num % 10
- reversed_num = reversed_num * 10 + digit
- num //= 10
- print("Reversed Number: " + str(reversed_num))
- user_input=input("\n\nTry again? (Yes/No): ")
- print("\n\n")
- if user_input.lower()=='no':
- print("Exit program.")
- break
- elif user_input.lower()=='yes':
- ret=True
- else:
- print("Wrong input.")
- ret=True
- if ret:
- continue
In the code above, we enclose the entire code with a while loop to ensure the continuation of the program. We set a variable to hold the reversed number. Additionally, we initialize a variable called 'reversed_num' and set its initial value to zero, which will handle the iterations later in the code. Finally, we use another while loop to iterate through the number and reverse it using logical arguments.
