With an Example Learn How To Fix: How do you render a template named home HTML with some data in Flask?

In web development with Flask, rendering HTML templates is a fundamental aspect.

Flask offers a straightforward approach through its templating engine to dynamically display content.

In this guide, we'll delve into the process of rendering a template named "home.html" with data in Flask.

Following these steps, you'll understand how to seamlessly integrate data into your web applications, enriching the user experience and empowering your Flask projects.

Let's embark on this journey to harness the power of Flask templating for creating dynamic and engaging web pages.

To render a template named "home.html" with some data in Flask, you can use the "render_template" function and pass data as keyword arguments.

Here's an example:

from flask import Flask, render_template

app = Flask(__name__)


@app.route('/')
def home():
    data = {'title': 'Welcome to my website!', 'content': 'This is the homepage.'}
    return render_template('home.html', data=data)


if __name__ == '__main__':
    app.run(debug=True)

In your "home.html" template, you can access the data using Jinja templating syntax, for example:

#home.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>{{ data.title }}</title>
</head>
<body>
    <h1>{{ data.title }}</h1>
    <p>{{ data.content }}</p>
</body>
</html>

This way, when you visit the route corresponding to the home function (in this case, '/'), Flask will render the "home.html" template with the provided data.
