  • When i execute the command python hello.py the first thing that would happen is that it would go to localhost:port/hello and it would return hello world without me having to go to a webpage and type localhost/hello

You can use webbrowser to automatically open http://localhost:5000 in a web browser when running your flask app:



import webbrowser

...



if __name__ == '__main__':

    webbrowser.open('http://localhost:5000')

    app.run()

You can use it like this:



def foo():

    pass



app.before_first_request(foo)


In the case where you want to run a script strictly on run, not just before the first request, this solution is good: Run code after flask application has started -- I guess you would use this for cold-start problems as well.
