<p><strong><a href="https://www.nature.com/articles/s41586-020-2649-2">Array programming with NumPy - the NumPy paper</a></strong></p> The NumPy paper is out, published in Nature. I found this enlightening: for an academic paper it’s very understandable, and it filled in quite a few gaps in my mental model of what NumPy is and which problems it addresses, as well as its relationship to the many other tools in the scientific Python stack. <p><small></small>Via <a href="https://twitter.com/numpy_team/status/1306268442450972674">@numpy_team</a></small></p> <p>Tags: <a href="https://simonwillison.net/tags/python">python</a>, <a href="https://simonwillison.net/tags/scipy">scipy</a>, <a href="https://simonwillison.net/tags/numpy">numpy</a></p>

<p><strong><a href="https://hacks.mozilla.org/2019/04/pyodide-bringing-the-scientific-python-stack-to-the-browser/">Pyodide: Bringing the scientific Python stack to the browser</a></strong></p> More fun with WebAssembly: Pyodide attempts (and mostly succeeds) to bring the full Python data stack to the browser: CPython, NumPy, Pandas, Scipy, and Matplotlib. Also includes interesting bridge tools for e.g. driving a canvas element from Python. Really interesting project from the Firefox Data Platform team. <p><small></small>Via <a href="https://news.ycombinator.com/item?id=19677721">Hacker News</a></small></p> <p>Tags: <a href="https://simonwillison.net/tags/mozilla">mozilla</a>, <a href="https://simonwillison.net/tags/pandas">pandas</a>, <a href="https://simonwillison.net/tags/python">python</a>, <a href="https://simonwillison.net/tags/scipy">scipy</a>, <a href="https://simonwillison.net/tags/webassembly">webassembly</a>, <a href="https://simonwillison.net/tags/numpy">numpy</a>, <a href="https://simonwillison.net/tags/pyodide">pyodide</a></p>

<p><strong><a href="https://bergvca.github.io/2017/10/14/super-fast-string-matching.html">Super Fast String Matching in Python</a></strong></p> Interesting technique for calculating string similarity at scale in Python, with much better performance than Levenshtein distances. The trick here uses TF/IDF against N-Grams, plus a CSR (Compressed Sparse Row) scipy matrix to run the calculations. Includes clear explanations of each of these concepts. <p><small></small>Via <a href="http://us2.campaign-archive.com/?u=e2e180baf855ac797ef407fc7&amp;id=3b186916c5/?u=e2e180baf855ac797ef407fc7&amp;id=3b186916c5&amp;awesome=no&amp;e=">Python Weekly - Issue 317</a></small></p> <p>Tags: <a href="https://simonwillison.net/tags/python">python</a>, <a href="https://simonwillison.net/tags/scipy">scipy</a></p>
