How to fix my code?

This is a Flask webpage, and in the home page, when I press the Go to Vehicle Comparison button there is a Not found error.

main.py code with all the routes:
from flask import Flask, request, render_template
import secrets
import os

app = Flask(name)
app.secret_key = secrets.token_hex(16)

Welcome to the Vehicle Comparison Tool

<section>
    <h2>About the Tool</h2>
    <p>This tool allows you to compare the costs of different electric and gasoline vehicles over a 5-year period. It takes into account various factors such as purchase price, fuel costs, and maintenance expenses.</p>

Why won’t the vehicle comparison page open? The terminal says Non-ASCII character xc3 on line 10 in main.py.

Hi there - can you share the url of the Glitch project, it may be easier for us to see the brokenness in action.

<a href="/vehicle-comparison" class="button">Go to Vehicle Comparison Tool</a>

that’s a link, which makes those clickable pieces of text. when you click it, the browser opens that URL by requesting it from the server. there’s another part to the request other than the URL, called the “method,” which is a short word. when opening links, browsers use the method “GET.”

@app.route(‘/compare-vehicles’, methods=[‘POST’])

(messed up quotes excepted) that’s a route that specifically handles the “POST” method. flask will skip over it if the request method is “GET” as in the case above.

and none of the other routes match, so it uses some built in fallback 404 responder.
