Bottle is a fine framework when you need to quickly start a small Python application and serve web calls from it. However, you will soon notice that browser calls to your application ask for favicon.ico. Of course you can ignore those calls, but what if you want to serve them too?
Once choice is to use server_static() and return the icon as described here. But what if you want to return a blank icon, since this is a quick hack anyway and you do not want to spend time searching for whatever icon or not?
Starting from the description of a blank favicon, you can add this to your code:
@get('/favicon.ico')
def get_favicon():
response.content_type = 'image/x-icon'
return "data:image/x-icon;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQEAYAAABPYyMiAAAABmJLR0T///////8JWPfcAAAACXBIWXMAAABIAAAASABGyWs+AAAAF0lEQVRIx2NgGAWjYBSMglEwCkbBSAcACBAAAeaR9cIAAAAASUVORK5CYII="
