What is great about this, is it can be used to reduce repetitive duplication between Models for an ORM and the Pydantic Models that FastAPI needs to describe serialization. … If you have very pure-data heavy abstractions where your input and outputs through the API are roughly equivalent to your database, this helps you avoid needing to duplicate tons of SQLAlchemy classes and Pydantic that look identical and now you need to keep them in sync (DRY issue).”</li> </ul> <p><strong>Michael #2:</strong> <a href="https://twitter.com/garettmd/status/1405005338726834177"><strong>No module named</strong></a></p> <ul> <li>via <a href="https://twitter.com/garettmd/status/1405005338726834177">Garett Dunn</a></li> <li>Website: <a href="https://nomodulenamed.com/"><strong>nomodulenamed.com</strong></a></li> <li>Get an error like <code>Python Error: No module named dateutil</code>, maybe you need <code>pip install python_dateutil</code> (<a href="https://nomodulenamed.com/m/dateutil">reference</a>)</li> </ul> <p><strong>Nick #3:</strong> <a href="https://jupyterlite.readthedocs.io/en/latest/"><strong>JupyterLite</strong></a></p> <ul> <li><a href="https://github.com/jtpio">Jeremy Tuloup</a></li> <li>JupyterLite is a JupyterLab distribution that <strong>runs entirely in the browser</strong> built from the ground-up using JupyterLab components and extensions.</li> <li>Python kernel backed by <a href="https://pyodide.org/">Pyodide</a> running in a Web Worker</li> <li>Kernels include <ul> <li>Python 3.8 (pyolite implementation)</li> <li>Javascript</li> <li>P5.js</li> </ul></li> <li>Data is written to in-browser storage</li> <li>Data doesn’t leave the browser unless you are using extensions or use browser’s <code>fetch</code> API</li> </ul> <p><strong>Brian #4:</strong> <a href="https://nbviewer.jupyter.org/github/dylanjcastillo/random/blob/main/cheatsheet_data_viz_python.ipynb"><strong>Lot of plots</strong></a></p> <ul> <li>Dylan Castillo</li> <li>Side by side comparison of plots.</li> <li>with: pandas, matplotlib, seaborn, plotly.express</li> <li>plotting: line, grouped bars, stacked bars, area, pie/donut, histogram, scatter, and box</li> <li>Many plotting articles talk about cool stuff you can do with a particular library.</li> <li>This is nice in that they all can do these things, so you can <ul> <li>see the output of each and compare</li> <li>see the code that goes into making each, and see what style of api you might like to work with</li> </ul></li> </ul> <p><strong>Michael #5:</strong> <a href="https://github.com/davidlatwe/montydb"><strong>Monty, Mongo tinified.
