How do I connect python to flask
To connect Python code to Flask, you can define a Flask application object and write functions that handle HTTP requests. Here’s an example of how to get started with connecting Python to Flask:
- Install Flask: If you haven’t already, you can install Flask by running the following command in your terminal or command prompt:Copy code
pip install flask
- Import Flask: In your Python code, you’ll need to import the Flask module:pythonCopy code
from flask import Flask
- Define your Flask app: Create a Flask app object by calling the Flask constructor:scssCopy code
app = Flask(__name__)The
__name__parameter is used to determine the root path of the application.
- Define a route: Use the
@app.route()decorator to define a function that handles HTTP requests to a specific URL:pythonCopy code
@app.route('/') def hello_world(): return 'Hello, World!'In this example, we define a route that handles HTTP GET requests to the root URL (“/”). The function returns a string that will be sent back to the client as the response.
- Run the app: Finally, you can run your Flask app by calling the
run()method on the app object:markdownCopy code
if __name__ == '__main__': app.run()This starts a development server that listens for incoming HTTP requests on port 5000 by default.
Here’s an example of what your code might look like when you put it all together:
from flask import Flask app = Flask(__name__) @app.route('/') def hello_world(): return 'Hello, World!' if __name__ == '__main__': app.run()
When you run this code and navigate to http://localhost:5000/ in your web browser, you should see the text “Hello, World!” displayed on the page.
This is just a simple example, but Flask is a powerful framework that can be used to build more complex web applications with database integration, authentication, and more.
