How to Rotate a String Using String Slicing in Python
In this tutorial, we will learn how to program "How to Rotate a String Using String Slicing in Python." The objective is to rotate the position of characters in a string using string slicing. This tutorial will guide you through the process step by step, showing you how to slice and rearrange a string. By the end, you will have a clear understanding of how to efficiently complete this task in Python.
This topic is straightforward to understand. Just follow the instructions I provide, and you will complete it with ease. The program I will demonstrate will show you the correct and efficient way to slice a string. 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============= Rotate a String Using String Slicing =============\n")
- s = input("Enter a String: ")
- d = int(input("Enter a digit[1-9]: "))
- ext_s = s + s
- n = len(s)
- left = ext_s[d:n + d]
- right = ext_s[n - d: 2 * n - d]
- print("Left Rotation:", left)
- print("Right Rotation:", right)
- opt = input("\nDo you want to try again?(yes/no): ")
- if opt.lower() == 'yes':
- ret=False
- elif opt.lower() == 'no':
- ret=True
- print("Exiting program....")
- else:
- print("Please enter yes/no:")
- break
- if ret == False:
- continue
The code allows the user to input a string and a number representing the number of positions to rotate the string. It performs two types of rotations: left and right, using string slicing. The left rotation involves shifting the characters from the beginning of the string to the end, while the right rotation shifts characters from the end of the string to the beginning. After each rotation, the resulting strings are displayed. The user is then asked whether they want to repeat the process with another string or exit the program. If the user chooses to continue, the process repeats; if they choose to exit, the program ends.
Output:
There you have it we successfully created How to Rotate a String Using String Slicing 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!
