1. Batteries Included, But They're Leaking Amber Brown Batteries Included, But They're Leaking -- Python Language Summit 2019
2. Let's Talk About The Stdlib. Batteries Included, But They're Leaking -- Python Language Summit 2019
3. Batteries included? Not really -- Python, by itself, is marginally useful. Batteries Included, But They're Leaking -- Python Language Summit 2019
4. typing requires mypy to be useful asyncio needs aiohttp to talk to the web* asyncio needs aiopg / aiomysql to talk to a database* *(without throwing away all the benefits of asynchronous IO) Batteries Included, But They're Leaking -- Python Language Summit 2019
5. ssl needs hacks to do TLS to IDNA domains???? pytz is basically non-optional six is non-optional for 2/3 compatible code Batteries Included, But They're Leaking -- Python Language Summit 2019
6. http.client literally says "use Requests" arrow , dateutil , moment , are all things people actually want to use Django, numpy , pandas bring people to Python, not Python people to them Batteries Included, But They're Leaking -- Python Language Summit 2019
7. Python's batteries are leaking Python's stdlib contains bugs that will never be fixed. Batteries Included, But They're Leaking -- Python Language Summit 2019
8. Python's batteries are leaking Python's stdlib contains past bugs that one can never rely on being fixed. Batteries Included, But They're Leaking -- Python Language Summit 2019
9. https://bugs.python.org/issue34155 Batteries Included, But They're Leaking -- Python Language Summit 2019
10. Depending on the Python stdlib is a liability for applications and libraries Batteries Included, But They're Leaking -- Python Language Summit 2019
11. Python-dev -> Python Release -> Distributions? Batteries Included, But They're Leaking -- Python Language Summit 2019
12. Two options: 1. Compile CPython yourself 2. Workaround hacks Batteries Included, But They're Leaking -- Python Language Summit 2019
13. The stdlib is 'too little, too late' in vital areas aka backport hell Batteries Included, But They're Leaking -- Python Language Summit 2019
14. socket.sendmsg means Twisted has a cext itertools has a pile of code in the docs as a 'recipe'???? functools needs backports for 2/3 compatible code Batteries Included, But They're Leaking -- Python Language Summit 2019
15. Python 2.7 is dead, but only if you're on python-dev Thanks, Red Hat! Batteries Included, But They're Leaking -- Python Language Summit 2019
16. The stdlib contains debatable "batteries", even on Python 3. Makes Python larger, harder to build, and less useful on constrained platforms. Batteries Included, But They're Leaking -- Python Language Summit 2019
17. pydoc distutils asyncore asynchat Batteries Included, But They're Leaking -- Python Language Summit 2019
18. IDLE & tkinter turtle sunau xdrlib 2to3 Batteries Included, But They're Leaking -- Python Language Summit 2019
19. Batteries Included, But They're Leaking -- Python Language Summit 2019
20. Provisional APIs are harmful Non-obvious stability traps Batteries Included, But They're Leaking -- Python Language Summit 2019
21. asyncio typing Batteries Included, But They're Leaking -- Python Language Summit 2019
22. Added stdlib modules disproportionately harms the ecosystem "why do we need this when it's in the stdlib?" Batteries Included, But They're Leaking -- Python Language Summit 2019
23. Added stdlib modules disproportionately harms the ecosystem The stdlib is where code goes to die Batteries Included, But They're Leaking -- Python Language Summit 2019
24. dataclasses has no reason to exist as a public API I spent the past four years explaining why incomplete and provisional asyncio didn't "kill" Twisted Batteries Included, But They're Leaking -- Python Language Summit 2019
25. CPython contribution is a tight funnel that misses out on huge amounts of potential contributors It's not a zero-sum game, but it's very close Batteries Included, But They're Leaking -- Python Language Summit 2019
26. CPython believes it's special enough to need special tools which give no benefit to the wider community blurb is CPython specific, despite the wide adoption of towncrier Batteries Included, But They're Leaking -- Python Language Summit 2019
27. Overlap of CPython devs and major library authors seems low A lot of the problems experienced by large library authors don't affect CPython Batteries Included, But They're Leaking -- Python Language Summit 2019
28. The frozen-in-time stdlib makes developing libraries harder. Twisted has to act like the stdlib is unpatched Batteries Included, But They're Leaking -- Python Language Summit 2019
29. The sprawling stdlib makes developing alternate alternatives harder. Every single module in the Python stdlib makes life harder for PyPy, PyBee, and IronPython/Jython/etc Batteries Included, But They're Leaking -- Python Language Summit 2019
