How to create flask web application

How to create flask web application:

 

Creating a Flask web application is a straightforward process. Here are the basic steps to get you started:

 

1. Install Flask: First, make sure you have Python installed on your system. Then, install Flask using pip:

pip install flask

 

2. Create a Flask App: Create a new Python file (e.g., app.py) and import Flask:

from flask import Flask app = Flask(__name__)

 

 3.  Define Routes: Use decorators to define routes for your app.

For example:

@app.route('/') def home():     return 'Hello, Flask!'

 

4. Run the App: In your terminal or command prompt, navigate to your project folder and run:

flask run

 

This will start your Flask app, and you can access it in your browser at http://localhost:5000.
