source venv/bin/activate pip install flask
app.py import flask app = flask.Flask(__name__) @app.route(‘/’) def index(): return
‘hai’ if __name__ == ‘__main__’: app.run()

TEMPLATING mkdir templates cd templates Jinja2 or whatever
index.html <!doctype> <html> <head> <title>Todos</title> </head> <body> <p>Hey you!</p> </body>
</html>
app.py @app.route(‘/’) def index(): return flask.render_template(‘index.html’)
app.py @app.route(‘/’) def index(): if ‘name’ in flask.request.args: name =
flask.request.args[‘name’] else: name = ‘Buffalo’ return flask.render_template(‘index.html’, name=name)
index.html <!doctype> <html> <head> <title>Todos</title> </head> <body> <p>Hey {{ name
