First, let's understand how Flask serves files:
public/myimage.jpg (or use whatever name you wish, but keep this directory!);python3 server.py) and point your browser to http://localhost:5000/public/myimage.jpg, it should display your image.server.py; start the web server, point your browser to http://localhost:5000/myimage2.jpg – it won't work… why?
Now, we want to move the html page from earlier tasks to be served by the Flask web server:
initial_design.html to the templates/ directory (we're using the default Flask convention);server.py to call render_template (see official quickstart guide) and actually serve your HTML file.
render_template symbol from the Flask library!
/google endpoint which automatically redirects to your favorite (or not) search engine!
