title: Python Plotly's Dash: How do you shut the web app running on a port or make changes to it? CTRL+C doesn't seem to be working
body: <p>Am using Plotly's Dash and trying to run the sample app code which they have provided here: <a href="https://plot.ly/dash/getting-started#dash-app-layout" rel="nofollow noreferrer">https://plot.ly/dash/getting-started#dash-app-layout</a></p>
  
  <p>Am having trouble with the ports. The code on being run shows this in the console: <a href="https://i.stack.imgur.com/s6Qz9.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/s6Qz9.jpg" alt="the console image"></a></p>
  
  <p>However , even after making changes to the code, the output in the web app shows no change.</p>
  
  <p>Basically, when I'm implementing a different code: the web app continues to display the output from the previous run!</p>
  
  <p>The CTRL+C doesn't seem to help and doesn't really quit or cause any change to the application. Please let me know what shall help.</p>
  
  <p>I ran the new code using a new port(8049) and that worked but doesn't solve the initial basic issue!</p>
