This tutorial will guide you step by step through the process of safely replacing blank spaces with hyphens. By the end of this tutorial, you will have a solid understanding of how to implement this task effectively in Python, helping you strengthen your problem-solving abilities and improve your 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 replacing blank spaces with hyphens. 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============= Replace All Blank Spaces with Hyphens =============\n")
 
    string = input("Enter a string: ")
    modified_string = string.replace(' ', '-')
    
    print("Modified string:")
    print(modified_string)
 
    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 program replaces all blank spaces in a string with hyphens. It takes user input, uses the `replace(' ', '-')` function to substitute spaces, and then displays the modified string. A loop allows repeated execution until the user chooses to exit.

Output:
