Brian #1: Python built-ins worth learning
- Trey Hunner
- “I estimate most Python developers will only ever need about 30 built-in functions, but which 30 depends on what you’re actually doing with Python.”
- “I recommend triaging your knowledge:
- Things I should memorize such that I know them well
- Things I should know about so I can look them up more effectively later
- Things I shouldn’t bother with at all until/unless I need them one day”
- all 69 built-in functions, split into
- commonly known
- overlooked by beginners
- learn it later
- maybe learn it eventually
- you likely don’t need these
- Highlighting some:
- overlooked by beginners
- sum, enumerate, zip, bool, reversed, sorted, min, max, any, all
- know it’s there, but learn it later:
- open, input, repr, super, property, issubclass, isinstance, hasattr, getattr, setattr, delattr, classmethod, staticmethod, next
- overlooked by beginners
- my notes
- I think getattr should be learned early on, because it’s default behavior is so useful. But can’t use it for dicts. Use
mydict.get(key, default)
for dictionaries.

Michael #2: Github sponsors and match
- Like Patreon but for GitHub projects
- 2x your sponsorship: Github matches! To boost community funding, we'll match contributions up to $5,000 during a developer’s first year in GitHub Sponsors with the GitHub Sponsors Matching Fund.
- 100% to developers, Zero fees: GitHub will not charge fees for GitHub Sponsors.
- Anyone who contributes to open source—whether through code, documentation, leadership, mentorship, design, or beyond—is eligible for sponsorship.
Brian #3: Build a REST API in 30 minutes with Django REST Framework
- Bennett Garner
- Very fast intro including:
- Set up Django
- Create a model in the database that the Django ORM will manage
- Set up the Django REST Framework
- Serialize the model from step 2
- Create the URI endpoints to view the serialized data
- Example is a simple hero db with hero name and alias.
Michael #4: Dependabot has been acquired by GitHub
- Automated dependency updates: Dependabot creates pull requests to keep your dependencies secure and up-to-date.
- I personally use and recommend PyUP: https://pyup.io/
- How it works:
- Dependabot checks for updates: Dependabot pulls down your dependency files and looks for any outdated or insecure requirements.
- Dependabot opens pull requests: If any of your dependencies are out-of-date, Dependabot opens individual pull requests to update each one.
- You review and merge: You check that your tests pass, scan the included changelog and release notes, then hit merge with confidence.
- Here's what you need to know:
- We're integrating Dependabot directly into GitHub, starting with security fix PRs 👮♂️
- You can still install Dependabot from the GitHub Marketplace whilst we integrate it into GitHub, but it's now free of charge 🎁
- We've doubled the size of Dependabot's team; expect lots of great improvements over the coming months 👩💻👨💻👩💻👨💻👩💻👨💻
- Paid accounts are now free, automatically.
Brian #5: spoof “New features planned for Python 4.0”
- Charles Leifer - also known for Peewee ORM
- This is funny, but painful. Is it too soon to joke about the pain of 2 to 3?
- A few of my favorites
- PEP8 will be updated. Line lengths will be increased to 89.5 characters. (compromise between 79 and 100)
- All new libraries and standard lib modules must include the phrase "for humans" somewhere in their title.
- Type-hinting has been extended to provide even fewer tangible benefits and will be called type whispering.
- You can make stuff go faster by adding async before every other keyword.
- Notable items left out of 4.0
- Still no
switch
statement. - No improvements to packaging.
- Still no
Michael #6: BlackSheep web framework
- Fast HTTP Server/Client microframework for Python asyncio, using Cython, uvloop, and httptools.
- Very Flask-like API. Interesting to consider the “popularity” of Flask vs Django in this context.
- Objectives
- Clean architecture and source code, following SOLID principles
- Intelligible and easy to learn API, similar to those of many Python web frameworks
- Keep the core package minimal and focused, as much as possible, on features defined in HTTP and HTML standards
- Targeting stateless applications to be deployed in the cloud
- High performance, see results from TechEmpower benchmarks (links in Wiki page)
- Also has an async client much like aiohttp.
Extras
Michael:
- Free courses in the Training mobile apps

Jokes
- How do you generate a random string? Put a first year Computer Science student in Vim and ask them to save and exit.
- Waiter: He's choking! Is anyone a doctor? Programmer: I'm a Vim user.
