WSGI is the specification of a common interface between web servers and web applications. Werkzeug Run the app and navigate to the /api/data endpoint to see that the static file is returned. Stop the app when you're done. doctype html> < title >Hello from Flask {% if name %} < h1 >Hello {{ name }}! {% else %} < h1 >Hello, World! {% endif %}

WSGI is an acronym for web server gateway interface which is a standard for Python web application development. It is considered the specification for the universal interface between the web server and web application. What is Jinja2? Think of Django views as the central point of the web app design. Django views accept HTTP requests and output HTTP responses while working with the other components to dynamically create that HTTP output. You can see that the code is now much simpler, and concerned only with data values, because the markup and formatting is all contained in the template. The completed code project from this tutorial can be found on GitHub: python-sample-vscode-flask-tutorial.

Start the debugger by selecting the Run> Start Debugging menu command, or selecting the green Start Debugging arrow next to the list ( F5): Tip: When using a different filename than app.py, such as webapp.py, you will need to define an environment variable named FLASK_APP and set its value to your chosen file. Flask's development server then uses the value of FLASK_APP instead of the default file app.py. For more information, see Flask command line interface. Run the app in the debugger Werkzeug is a WSGI toolkit that implements requests, response objects, and utility functions. This enables a web frame to be built on it. The Flask framework uses Werkzeg as one of its bases. jinja2 A local Python 3 programming environment, follow the tutorial for your distribution in How To Install and Set Up a Local Programming Environment for Python 3 series for your local machine. In this tutorial we’ll call our project directory flask_blog. Each framework has a different way to put together its routes, models, views, database interaction, and overall application configuration. I'll describe those aspects of each framework in this series, which will begin with Flask. Flask startup and configuration

In the Integrated Terminal, run the app by entering python -m flask run, which runs the Flask development server. The development server looks for app.py by default. When you run Flask, you should see output similar to the following: (.venv) D: \p y \\ hello_flask>python -m flask run * Environment: production WARNING: Do not use the development server in a production environment. Use a production WSGI server instead. * Debug mode: off * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit) To fix this error, create a directory called templates inside your flask_blog directory. Then inside it, open a file called index.html for editing: In VS Code, create a new file in your project folder named app.py using either File> New from the menu, pressing Ctrl+N, or using the new file icon in the Explorer View (shown below). The application is running locally on the URL http://127.0.0.1:5000/, 127.0.0.1 is the IP that represents your machine’s localhost and :5000 is the port number.Copy that line into the > prompt at the bottom of the debug console, and try changing the formatting: now.strftime( "%a, %d %B, %Y at %X" ) 'Wed, 31 October, 2018 at 18:13:39' now.strftime( "%a, %d %b, %Y at %X" ) 'Wed, 31 Oct, 2018 at 18:13:39' now.strftime( "%a, %d %b, %y at %X" ) 'Wed, 31 Oct, 18 at 18:13:39' In the list that appears, select html. The option may appear as "html.json" in the Existing Snippets section of the list if you've created snippets previously. In a given web application, you may want to be able to express relationships between objects. In the To-Do List example, users own multiple tasks, and each task is owned by only one user. This is an example of a "many-to-one" relationship, also known as a foreign key relationship, where the tasks are the "many" and the user owning those tasks is the "one." In Flask, views appear as functions; for example, see the hello_world view above. For simplicity, here it is again: @app.route('/')
