python flask how to remove last character from string

from flask import Flask

app = Flask(__name__)

@app.route('/')
def remove_last_character():
    original_string = "Hello World"
    modified_string = original_string[:-1]
    return f"Original String: {original_string}<br>Modified String: {modified_string}"

if __name__ == '__main__':
    app.run(debug=True)

1. Import the Flask class from the flask module.
2. Create a Flask application instance.
3. Define a route '/' using the @app.route() decorator.
4. Create a function remove_last_character() to handle requests to this route.
5. Initialize an original_string variable with the value "Hello World".
6. Use slicing ([:-1]) to create a modified_string that excludes the last character of the original_string.
7. Return a string displaying the original string and the modified string in the browser.
8. Start the Flask application in debug mode if the script is executed directly.
