My Python setup used to change a lot, as I would find ad-hoc solutions for my needs. These days I’ve settled on a Python setup that satisfies pretty much all of my different use cases and is easy to use. It is composed of these tools:<\/p>\n
Pyenv<\/a> is nice in the sense that it makes it a breeze to try and use new Python versions that don’t come bundled with your OS. e.g. try out the Walrus operator<\/a> and Python 3.8:<\/p>"},{"title":"Designing Pythonic APIs","link":"https:\/\/noamelf.com\/posts\/designing-pythonic-apis\/","pubDate":"Fri, 05 Aug 2016 00:00:00 +0000","guid":"https:\/\/noamelf.com\/posts\/designing-pythonic-apis\/","description":" Learning from Kenneth Reitz’s Requests<\/a><\/em><\/p>\n When writing a package (library), providing it with a good API, is almost as important as its\nfunctionality itself (well, at least if you want some adoption), but what makes a good API?

This was the first time I ever experienced anything of that sort so I was pretty excited about it. I read a lot of blog posts and Stack Overflow questions about optimization but still wasted some time on optimizing the wrong parts. Following is the lessons I learned, and some pitfalls that you can avoid on your next optimization task.<\/p>\n The first you want to do when optimizing anything is to be able to measure it’s performance. I looked for a Python based (my favorite language) load testing solution and found Locust<\/a>. Locust is a quick and easy package to run a threaded load testing programs with nothing but Python code. Everything was great until I sadly realized that Locust aggregates the results, meaning: I couldn’t get a raw<\/em> CSV to store and analyze later on using graph tools of sorts.<\/p>"},{"title":"Teaching Python to Haredim (and a CNN visit)","link":"https:\/\/noamelf.com\/posts\/ravtech-and-cnn\/","pubDate":"Fri, 10 Jul 2015 14:13:48 +0000","guid":"https:\/\/noamelf.com\/posts\/ravtech-and-cnn\/","description":" For the last couple of months I’ve been involved in a great project: getting Haredic<\/a> (ultra-orthodox jews) man into the software world!<\/p>\n Last week, we got an exciting visit from Oren Libermann, a CNN reporter, who published this nice story<\/a>.<\/p>\n My job in the training process is to teach them the Python programing language.
