This defines the code which runs when the home page of the flask app is reached and needs to be added between the imports and the app.run lines within app.py. Running the app. Finally, we can run the app and view it using python app.py and navigating to in a web browser to view it. Flask is a very famous micro web framework written in Python. It was created by Armin Ronacher. It is based on the Werkzeug WSGI toolkit and the Jinja2 template engine.
Flask is a very popular and powerful framework for building web applications. Over the last years, people used it to create REST API that work well with decoupled, modern front-end applications.
Spotify student free trial with hulu. One challenge that backend development teams often face, is how to make it easy for front-end developers, wethere internal or with a distant community, to create API-compliant clients (web app, mobile app or even CLI tools..)
In the wild, they are many good examples of well-documented APIs.. Take the Twitter API : the docs are great, user-friendly and cover all the available endpoint with tips and examples. Any fresh CS student could write a small Python tool using it, just by following the documentation and its examples.
Spotify Api Data![]()
At @Ooreka, we decided to follow the OpenAPI (fka Swagger 2.0) specification to build a solid documentation for our Flask-powered micro-services APIs. Let's dive in.
3.2.1. Doc!
Thanks to the apispec lib, you can automagically generate a specification file (commonly named
swagger.json ) form your Flask code. Some other libraries can do a lot of magic for you, but apispec is really simple to use and can sit next to your code without interfering with it.
It supports Marshmallow and Flask, allowing you to re-use your code to generate a proper documentation !
Let's write our generation script, e.g.
app/scripts/openapi.py :
Here, we first create a new APISpec instance with some details about our API.
Then, we add our definitions (here, we are using Marshmallow to define how our API will serialize/deserialize data) with APISpec.definition() .Finally, we add our routes to our API specification using APISpec.add_path() . apispec will parse your route functions docstrings, so make sure your add some OpenAPI YaML stuff here, as in :Spotify not downloading app.
You will end up with a valid JSON API specification. Now, let's see how to bootstrap an HTML version to show it to the world!
Browerify-ing all this
A really cool tool to do that is the ReDoc Javascript library from the guys at APIs.guru. We'll use it to present the generated JSON specification in a convenient way.
Redoc is basically a single, minified JS file you can include in a bare
index.html file and tell it where your swagger.json is located. It uses a really neat 3 columns design : a navigation sidebar, a wide center section with your API endpoints definitions and a third column dedicated to requests or responses samples and examples.
Yep, that was quick. Check out a real-world example here.
Wrapping it up![]()
The OpenAPI offers many options I didn't cover here for brievity and simplification. You can add your server's real endpoints to the doc, add many details about the parameters and responses of your routes, provide example in your routes functions docstring that will be parsed and added to your spec, etc..
As a final tip, head to the Flask CLI documentation to see how easily you can hook your generation script into the command line interface of Flask (this will give you some badass command like
FLASK_APP=main.py flask generate_doc ). Oh, and be sure to put this into your Continuous Integration routine to keep your API documentation up-to-date with your API!
Cheers!

Python app created with Flask
Flask App Spotify Api Login
In this tutorial you’ll learn how to build a web app with Python. We’ll use a micro-framework called Flask.
Why Flask?

Python Flask: Make Web Apps with Python
Create a file called hello.py
Finally run the web app using this command: https://treehit628.weebly.com/free-spotify-account-premium-2016.html.
Open http://localhost:5000/ in your webbrowser, and “Hello World!” should appear.
Creating URL routesSpotify Api TutorialURL Routing makes URLs in your Web app easy to remember. We will now create some URL routes:
Copy the code below and save it as app.py
Restart the application using:
Try the URLs in your browser:

Python Flask: Make Web Apps with Python Style Flask Pages
We will separate code and User Interface using a technique called Templates. We make the directory called /templates/ and create the template:
The Python Flask app with have a new URL route. We have changed the default port to 80, the default HTTP port:
You can then open : http://127.0.0.1/hello/Jackson/
Styling the template
Do you want some better looking template? We modify the file:
We then create layout.html which defines the look of the page. (You may want to split the stylesheet and layout.html file). Copy this as layout.html
Restart the App and open the url. http://127.0.0.1/hello/Jackson/ python webapp flask
You can pick any name other than Jackson.

Python Flask: Make Web Apps with Python Passing Variables
Lets display random quotes instead of always the same quote. We will need to pass both the name variable and the quote variable. To pass multiple variables to the function, we simply do this:
Our new test.html template will look like this:
We will need to pick a random quote. To do so, we use this code: https://treehit628.weebly.com/download-spotify-podcasts-to-mp3-online.html.
The first thing you see is we have defined an array of multiples quotes. These can be accessed as quote[0], quote[1], quote[2] and so on. The function randint() returns a random number between 0 and the total number of quotes, one is subtracted because we start counting from zero. Finally we set the quote variable to the quote the computer has chosen. Copy the code below to app.py:
When you restart the application it will return one of these quotes at random.

Whats next?
You could link your site with a database system such as MySQL, MariaDb or SQLite. You can find an SQLite tutorial here. Enjoy creating your application! Comments are closed.
