Michael #2: Introduction to ASGI: Emergence of an Async Python Web Ecosystem
- by Florimond Manca
- Python growth is not just data science
- Python web development is back with an async spin, and it's exciting.
- One of the main drivers of this endeavour is ASGI , the Asynchronous Standard Gateway Interface.
- A guided tour about what ASGI is and what it means for modern Python web development.
- Since 3.5 was released, the community has been literally async-ifying all the things. If you're curious, a lot of the resulting projects are now listed in aio-libs and awesome-asyncio .
- An overview of ASGI
- Why should I care? Interoperability is a strong selling point, there are many more advantages to using ASGI-based components for building Python web apps.
- Speed: the async nature of ASGI apps and servers make them really fast (for Python, at least) — we're talking about 60k-70k req/s (consider that Flask and Django only achieve 10-20k in a similar situation).
- Features: ASGI servers and frameworks gives you access to inherently concurrent features (WebSocket, Server-Sent Events, HTTP/2) that are impossible to implement using sync/WSGI.
- Stability: ASGI as a spec has been around for about 3 years now, and version 3.0 is considered very stable. Foundational parts of the ecosystem are stabilizing as a result.
- To get your hands dirty, try out any of the following projects:
- uvicorn: ASGI server.
- Starlette: ASGI framework.
- TypeSystem: data validation and form rendering
- Databases: async database library.
- orm: asynchronous ORM.
- HTTPX: async HTTP client w/ support for calling ASGI apps (useful as a test client).

Michael #4: Assembly
- via Luiz Honda
- Assembly is a Pythonic Object-Oriented Web Framework built on Flask, that groups your routes by class
- Assembly is a pythonic object-oriented, mid stack, batteries included framework built on Flask, that adds structure to your Flask application, and group your routes by class.
- Assembly allows you to build web applications in much the same way you would build any other object-oriented Python program.
- Assembly helps you create small to enterprise level applications easily.
- Decisions made for you + features: github.com/mardix/assembly#decisions-made-for-you--features
Examples, root URLs:
# Extends to Assembly makes it a route automatically
# By default, Index will be the root url
# index is the entry route
# -> /
return "welcome to my site"
# method name becomes the route
# -> /hello/
return "I am a string"
# undescore method name will be dasherize
# -> /about-us/
return "I am a string"
Example of /blog.
# The class name is part of the url prefix
# This will become -> /blog
# index will be the root
# -> /blog/
"title": "title 1",
# with params. The order will be respected
# -> /comments/1234/
# 1234 will be passed to the id

Joke: The failed pickup line
- A girl is hanging out at a bar with her friends.
- Some guy comes up to her an says: “You are the ; to my line of code.”
- She responds, “Get outta here creep, I code in Python.”
