flask return html
Certainly! Here's an example of how to use Flask to return HTML:
- Import Flask: Import the Flask class from the
flaskmodule.
python
from flask import Flask
- Create an instance: Create an instance of the Flask class.
python
app = Flask(__name__)
- Define a route: Use the
@app.route()decorator to define a route. This associates a URL with a function that will be called when the URL is visited.
python
@app.route('/')
def index():
return 'Hello, this is the homepage!'
- Create an HTML route: Define another route for returning HTML content.
python
@app.route('/html')
def html_page():
return '''
<html>
<head>
<title>Flask HTML Example</title>
</head>
<body>
<h1>Hello, this is an HTML page!</h1>
</body>
</html>
'''
- Run the application: Use
app.run()to start the Flask development server.
python
if __name__ == '__main__':
app.run(debug=True)
Explanation: This code sets up a basic Flask application with two routes. The first route, '/', is the root route and returns a simple text message when visited. The second route, '/html', returns an HTML page when visited, created as a multi-line string in Python. When the script is executed, the Flask development server starts, allowing you to visit these routes in a web browser.
