Content warning:Advent of Code - Day 2 (both parts)
I just completed "Gift Shop" - Day 2 - Advent of Code 2025 #AdventOfCode #Python #PythonMorsels
https://adventofcode.com/2025/day/2
I used a Python Morsels exercise to solve this one: https://www.pythonmorsels.com/exercises/008c3f7419944ed781eb4924483bff35/?level=intermediate
I re-implement parse_ranges from scratch and ended up using a hack that @nedbat calls a "Python gargoyle": https://nedbatchelder.com/blog/201802/a_python_gargoyle.html
It took a few seconds to run, but I'm fine with that. Why over-engineer to clean up after a mischievous elf's one-time mishap?

I have created a simplified RSS feed for my #AdventOfCode solutions & explanations.
Unfortunately they are not full text versions as it's not tied to my publishing system but rather a manual process to add new entries.
So if you want to follow my solutions, plug the URL to your favourite RSS reader and follow me along as I solve puzzles and use them to teach #Python.

Bài viết khám phá các tính năng typing nâng cao của Python (như never types, type guards, concatenate). Mặc dù thường bị bỏ qua, chúng có thể giúp giảm tới 15% lỗi và cải thiện khả năng bảo trì mã nguồn đáng kể.

On a slight tangent I have just noticed that on the TI 84 int(x) is NOT the same as in python. Who is to blame for this? #ti84 #python #horror

Django security releases issued: 5.2.9, 5.1.15, and 4.2.27
In accordance with our security release policy, the Django team is issuing releases for Django 5.2.9, Django 5.1.15, and Django 4.2.27. These releases address the security issues detailed below. We encourage all users of Django to upgrade as soon as possible.
CVE-2025-13372: Potential SQL injection in <tt class="docutils literal">FilteredRelation</tt> column aliases on PostgreSQL
<tt class="docutils literal">FilteredRelation</tt> was subject to SQL injection in column aliases, using a suitably crafted dictionary, with dictionary expansion, as the <tt class="docutils literal">**kwargs</tt> passed to <tt class="docutils literal">QuerySet.annotate()</tt> or <tt class="docutils literal">QuerySet.alias()</tt> on PostgreSQL.
Thanks to Stackered for the report.
This issue has severity "high" according to the Django security policy.
CVE-2025-64460: Potential denial-of-service vulnerability in XML serializer text extraction
Algorithmic complexity in <tt class="docutils literal">django.core.serializers.xml_serializer.getInnerText()</tt> allowed a remote attacker to cause a potential denial-of-service triggering CPU and memory exhaustion via specially crafted XML input submitted to a service that invokes XML <tt class="docutils literal">Deserializer</tt>. The vulnerability resulted from repeated string concatenation while recursively collecting text nodes, which produced superlinear computation resulting in service degradation or outage.
Thanks to Seokchan Yoon (https://ch4n3.kr/) for the report.
This issue has severity "moderate" according to the Django security policy.
Affected supported versions

Two pandas dataframes. Both should have unique indexes. Left joining produces a result longer than either. WAT. Tune in next time for the thrilling conclusion. #Python #PythonMysteries
