How to Create a String from First and Last Characters in Python
In this tutorial, we will learn how to program "How to Create a String from First and Last Characters in Python." The objective is to generate a random string based on the first and last characters of the given input. This tutorial will guide you step by step through the entire process of creating the string. By the end of this tutorial, you will have a solid understanding of how to implement this task effectively, helping you strengthen your problem-solving abilities and improve your Python coding skills.
This topic is straightforward to understand. Simply follow the instructions provided, and you will complete it with ease. The program will guide you step by step through the process of calculating the gravitational force. So, let’s dive into the coding process!
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 that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.- while True:
- print("\n=============== Create a String from First and Last Characters ===============\n")
- string = input("Enter a string: ")
- if len(string) < 2:
- print("String is too short to form a new one.")
- else:
- new = string[:2] + string[-2:]
- print("Newly formed string is:", new)
- opt = input("\nDo you want to try again? (yes/no): ").strip().lower()
- if opt == 'no':
- print("Exiting program...")
- break
- elif opt != 'yes':
- print("Invalid choice. Exiting program...")
- break
This Python program creates a new string using the first two and last two characters of a user-provided input string. If the entered string is shorter than two characters, it alerts the user that it’s too short to form a new one. Otherwise, it extracts the first two characters and the last two characters, concatenates them, and displays the newly formed string. The program runs in a loop, allowing repeated use until the user chooses to exit.
Output:
There you have it we successfully created How to Create a String from First and Last Characters in Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
