You are posting to the entry() function, while your entry_post() function listens to a different route; it is registered to only listen to /data, not /:

@app.route("/data", methods=['POST'])
def entry_post():

The / route doesn't accept POST, by default only GET, HEAD and OPTIONS are allowed.

Adjust your form accordingly:

<form action="/data" autocomplete="on" method="POST">

Take into account that Flask does not reload your source unless you enable debugging:

app.run(debug=True)
