Python code in Flask's HTML curly braces don't work
Question
Whenever I try to write code in curly braces it doesn't work, shows error 404 page not found. I copied the code from 9:48 in this video .
from flask import Flask, redirect, url_for, render_template
app = Flask(__name__)
@app.route("/<name>")
def home(name):
return render_template("index.html")
if __name__ == "__main__":
app.run()
<!DOCTYPE html>
<html>
<head>
<title>Home Page</title>
</head>
<body>
<h1>Home Page!</h1>
{% for x in range(10) %}
{% if x % 2 == 1 %}
<p>x</p>
{% endif %}
{% endfor %}
</body>
</html>
Also this is printed in the terminal below some other stuff which I think is why this is happening.
jinja2.exceptions.UndefinedError: 'x' is undefined

Ok so the problem was that I had several different terminals open and it seemed that I used an older version, where an error was in the code. To fix this, simply kill all of the active terminal instances and then run your script by opening a new terminal with VS Code -> Terminal -> New terminal or with Ctrl+Shift+`.
