from flask import Flask

app = Flask(__name__)

def remove_last_character():

if __name__ == '__main__':
  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.
