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:

Examples, root URLs:

    # Extends to Assembly makes it a route automatically
# By default, Index will be the root url
class Index(Assembly):

# index is the entry route
# -> /
def index(self):
return "welcome to my site"

# method name becomes the route
# -> /hello/
def hello(self):
return "I am a string"

# undescore method name will be dasherize
# -> /about-us/
def about_us(self):
return "I am a string"

Example of /blog.

    # The class name is part of the url prefix
# This will become -> /blog
class Blog(Assembly):

# index will be the root
# -> /blog/
def index(self):
return [
"title": "title 1",
"content": "content"

# with params. The order will be respected
# -> /comments/1234/
# 1234 will be passed to the id
def comments(self, id):
return [

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.”
