Step-by-Step Tutorial: Creating a Python Flask CRUD Application
Introduction to Flask Framework
- Start by downloading and installing Python 3.6 from the official website.
- Choose an IDE, such as PyCharm, and download the community version which is free.
- You will also need a web server for hosting your Flask application.
Setting Up the Flask Application
- Open your preferred IDE and create a new project named "FlaskCRUDApplication."
- Install Flask by running the command
pip install flaskin your terminal. - Create a new Python file and name it
app.py. - Import Flask by adding
from flask import Flaskat the beginning of yourapp.pyfile. - Create a Flask application instance by initializing Flask:
app = Flask(__name__).
Creating Routes in Flask
- Define a route by using the
@app.routedecorator followed by the URL and HTTP method. - For example, you can create a route that returns "Hello Flask" by writing:
@app.route('/')
def hello():
return 'Hello Flask'
Running the Flask Application
- Run the Flask development server by adding the following code at the end of your
app.pyfile:
if __name__ == '__main__':
app.run(debug=True)
- Launch your Flask application by running the
app.pyfile. - Access your Flask application in a web browser by visiting
http://localhost:5000.
Conclusion

- This tutorial serves as an introduction to Flask framework and sets the foundation for building a CRUD web application using Python.
By following these steps, you have successfully set up a basic Flask application and created your first route. Feel free to expand upon this project to build a complete CRUD web application as demonstrated in the video.
