python how to automatically restart flask sever

To automatically restart the Flask server, you can use a tool called "Flask-Script" which provides support for creating command-line interfaces. Here's how to do it:

First, install Flask-Script using pip:

pip install Flask-Script

Then, create a file, for example, manage.py and add the following code to it:

from flask_script import Manager
from your_application import app

manager = Manager(app)

@manager.command
def runserver():
    app.run()

if __name__ == '__main__':
    manager.run()

Now, you can start the Flask server using the following command:

python manage.py runserver

This will automatically restart the Flask server whenever changes are made to the code.
