Annotated explanation of David Beazley’s dataklasses (via) David Beazley released a self-described “deliciously evil spin on dataclasses” that uses some deep Python trickery to implement a dataclass style decorator which creates classes that import 15-20 times faster than the original. I put together a heavily annotated version of his code while trying to figure out how all of the different Python tricks in it work.

I've always believed that a book, even a technical book, should try to tell a cohesive story. The challenge is that as Python has grown in popularity, it has really turned into three different languages--each with their own story. There is a whimsical Python for scripting and tinkering, a quirky Python for asynchronous programming and networking, and a serious Python for enterprise applications. Sometimes these stories intersect. Sometimes not.

Reexamining Python 3 Text I/O. Python 3.1’s IO performance is a huge improvement over 3.0, but still considerably slower than 2.6. It turns out it’s all to do with Python 3’s unicode support: When you read a file in to a string, you’re asking Python to decode the bytes in to UTF-8 (the new default encoding) at the same time. If you open the file in binary mode Python 3 will read raw bytes in to a bytestring instead, avoiding the conversion overhead and performing only 4% slower than the equivalent code in Python 2.6.4.
