Special guest: Brandon Braner Brain #1: pip Environmental Variables The problem with snakes on a plane → no internet Situation: want to work on some code on a plane project set up to use tox, which creates venvs, and pip installs dependencies from pypi.org. but… no internet Preflight work: run tox with an internet connection copy everything from all of the “site-packages” directories under “.tox” into a “wheels” directory or whatever you want to call it. set environmental variables: PIP_FIND_LINKS=file:/Users/okken/wheels PIP_NO_INDEX=1 Try this out first BEFORE getting on the plane, to make sure you didn’t miss anything. In flight: tox works fine now, using local dir as index Thanks Paul Ganssle for helping with this. All command line flags for pip are available as env variables: “pip’s command line options can be set with environment variables using the format PIP_[HTML_REMOVED] . Dashes (-) have to be replaced with underscores (_).” Michael #2: Extra, Extra, 6x Extra, hear all about it Michael’s Pydantic talk Little Automation Tools in Python episode A Day in Code- Python: Learn to Code in Python through an Illustrated Story Released by Shari Eskenas TabNine AI complete macOS photos follow up jinja-partials chameleon-partials fastapi-chameleon Brandon #3: Kaggle 30 Days of Machine Learning What is Kaggle Find and publish data sets Explore and build models in a web-based data-science environment(Jupyter Notebooks) Work with other data scientists and machine learning engineers Enter competitions to solve data science challenges.

And, you can test all of the tox environments locally. name: Python package on: [push, pull_request] jobs: build: runs-on: ubuntu-latest strategy: matrix: python: [3.7, 3.8, 3.9, 3.10-dev] steps: - uses: actions/checkout@v2 - name: Setup Python uses: actions/setup-python@v2 with: python-version: ${{ matrix.python }} - name: Install Tox and any other packages run: pip install tox - name: Run Tox run: tox -e py Michael #5: python-vendorize via Patrick Park Vendoring a dependency means basically copying it into your package or your app rather than installing and importing it externally. Here’s a simple way to do that. python-vendorize allows pure-Python dependencies to be vendorized vendorize.toml might look something like: target = "your_app/_vendor" packages = [ "six", ] run python-vendorize in the same directory as vendorize.toml In your_app.py, six can be imported from _vendor: from ._vendor import six Brandon #6: Supabase and the new Python library Supabase is an open source Firebase Alternative Postgres Database, Authentication, instant APIs, realtime subscriptions and Storage uses: https://postgrest.org/en/stable/ for rest api access to your database GoTrue from Netlify for handling user authentication https://github.com/netlify/gotrue Realtime client built in Elixir to listen to Postgres changes. https://github.com/supabase/realtime Supabase local so you don’t need internet to develop your project https://supabase.io/docs/guides/local-development Extras The Baked Data architectural pattern Simon Willison “Baked Data: bundling a read-only copy of your data alongside the code for your application, as part of the same deployment” Released service - released.sh Joke The (tech) circle of life
