I tried installing wampp server, but it did not help. Can anyone please help me . I have my program but unable to see the results??
Or is there is a way to see that result without server?
are you trying to run a dash app on your PC as part of development. if you are on windows just open cmd, navigate to the folder you have placed the app, more like
cd Documents
cd davelopment
then you can run the application as
python app.py
where app is the name you have given to the program you are running. from there you can input http://localhost:8888 where the 8888 is the port you are asked to open by dash or http://127.0.0.1:8888/ in your web browser(mozilla firefox, google chrome etc)
thank you so much 
it helped
