You might want to check out the "Extension editor" inside the dev-hub:

Do you want to embed the whole application or just a chart?
If you just want to import a chart you might want to use the "Single configurator" from your dev-hub. You might import multiple charts this way but if you want something more specific you might also want to look into mashups.
Just remember to uncheck "Disable interaction" in case you want the chart to be interactive.
Hello Mohamed ,
try creating a widget containing an iframe element (just open /dev-hub, go to widgets and add to your existing widget-library or create a new one):
<iframe src="https ://LINK-TO-YOUR-PYTHON-SITE" style="width: 100%; height: 100%;"></iframe>
You can also create and use custom-settings inside a widget which makes it possible to display different webpages for each object.
