Typed Python library performance Typed Python library performance By seb july 21,2025. A few months ago, we launched a second version of our programming library: the Typed Python library. In a previous post, we explained the new features. This week, we'll be analyzing the difference in performance between the two versions. From a technical point of view, these two libraries work completely differently. The "traditional" library is split into two layers: a high-level layer that implements the Yoctopuce objec

Tall, Snarky Canadian 18 Jul 2020 8 min read syntactic sugar Unravelling attribute access in Python I wonder how many people realize that Python has a lot of syntactic sugar ? I'm not claiming it's like a Lisp-based language where the syntax is as bare bones as possible (although the Lisp comparison is not entirely unfounded ), but much of Python's syntax isn't technically needed as under the hood a good chunk of it is just function calls. But so what? Why care about how Python devolves into less syntax and

# python I’ve been doing a fair amount of HBase work lately at $work, not least of which is pybase , a python module that encapsulates Thrift and puts it under an API that looks more or less like the Cassandra wrapper pycassa (which we also use). When running an HBase cluster, one must very quickly learn the stack from top to bottom and be ready to fix the metadata when catastrophe strikes. Most of the necessary information about HBase regions is stored in the .META. table; unfortunately some of the value
