Using CPython’s Embeddable Zip File
On the download page for CPython 3.5.1, you'll see a wide range of options. Not all of these are well explained, especially for Windows users who have seven (seven!) choices.

How to deal with the pain of “unable to find vcvarsall.bat”
Python's packaging ecosystem is one of its biggest strengths, but Windows users are often frustrated by packages that do not install properly. One of the most common errors you'll see is this one: As far as errors go, "unable to find vcvarsall.bat" is not the most helpful. What is this mythical batch file? Why do I need it?

Idiomatic Python: comprehensions
Idiomatic Python: comprehensions
We're lucky to have a few people on our team who have been programming in Python for quite a while (I myself have been using the language now for over 15 years). Over the course of time we have picked up various idioms for programming in Python that may not be obvious or widely known for various reasons. To help share some of this knowledge we...
