Michael #1: Why I Still Use Python Virtual Environments in Docker)

• by Hynek Schlawack

• I was going to cover Production-ready Docker Containers with uv) but decided to take this diversion instead.

• Spend a lot of time thinking about the secondary effects of what you do.

• venvs are well known and well documented. Let’s use them.

Brian #2: Python Developer Survey Results)

• “… official Python Developers Survey, conducted as a collaborative effort between the Python Software Foundation and JetBrains.”

• Python w/ Rust rising, but still only 7%

• ““The drop in HTML/CSS/JS might show that data science is increasing its share of Python.” - Paul Everitt

• 37% contribute to open source. Awesome.

• Favorite Resources: Podcasts

• Lots of familiar faces there. Awesome.

• Perhaps I shouldn’t have decided to move “Python Test” back to Test & Code)

• Usage

• “Data analysis” down, but I think that’s because “data engineering” is added.

• Data, Web dev, ML, devops, academic,

• Testing is down 23%

• Python Versions

• Still some 2 out there

• Most folks on 3.10-3.12

• Install from: mostly python.org

• Frameworks

• web: Flask, Django, Requests, FastAPI …

• testing: pytest, unittest, mock, doctest, tox, hypothesis, nose (2% might be the Python 2 people)

• Data science

• 77% use pandas, 72% NumPy

• OS: Windows still at 55%

• Packaging:

• venv up to 55%

• I imaging uv will be on the list next year

• requirements.txt 63%, pyproject.toml 32%

• virtual env in containers? 47% say no

Michael #3: Anaconda Code add-in for Microsoft Excel)

• Run their Python-powered projects in Excel locally with the Anaconda Code add-in

• Powered by PyScript, an Anaconda supported open source project that runs Python locally without install and setup

• Features

• Cells Run Independently

• Range to Multiple Types

• init.py file is static and cannot be edited, with Anaconda Code, users have the ability to access and edit imports and definitions, allowing you to write top-level functions and classes and reuse them wherever you need.

• A Customizable Environment

Brian #4: Disabling Scheduled Dependency Updates)

• David Lord

• Interesting discussion of as they happen or batching of upsates to dependencies

• dependencies come in

• requirements files

• GH Actions in CI workflows

• pre-commit hooks

• David was seeing 60 PRs per month when set up on monthly updates (3 ecosystems * 20 projects)

• new tool for updating GH actions: gha-update), allows for local updating of GH dependencies

• New process

• Run pip-compile, gha-update, and pre-commit locally.

• Update a project’s dependencies when actively working on the project, not just whenever a dependency updates.

• Note that this works fine for dev dependencies, less so for security updates from run time dependencies. But for libraries, runtime dependencies are usually not pinned.

Extras

Brian:

• Test & Code) coming back this week

• Code in a Castle event)

• Python Bytes badge spotting)

• Guido’s post removed for moderation)
