Python is one of the most widely adopted programming languages in the world. Yet, because of it’s ease and simplicity to just “get something working”, it’s also one of the most underappreciated. If you search for Top 10 Advanced Python Tricks on Google or any other search engine, you’ll find tons of blogs or LinkedIn articles going over trivial (but still useful) things like generators or tuples. However, as someone who’s written Python for the past 12 years, I’ve come across a ...| Edward Li's Blog

You know Python is essential for a data engineer. Does anyone know how much one should learn to become a data engineer? When you're in an interview with a hiring manager, how can you effectively demonstrate your Python proficiency? Imagine knowing exactly how to build resilient and stable data pipelines (using any language). Knowing the foundational ideas for data processing will ensure you can quickly adapt to the ever-changing tools landscape. In this post, we will review the concepts you n...| www.startdataengineering.com

The Python standard library is full of underappreciated gems. One of them allows for simple and elegant function dispatching based on argument types. This makes it perfect for serialization of arbitrary objects – for example to JSON in web APIs and structured logs.| Hynek Schlawack
If your Python decorator unintentionally changes the signatures of my callables or doesn’t work with class methods, it’s broken and should be fixed. Sadly most decorators are broken because the web is full of bad advice.| Hynek Schlawack
namedtuple has been around since forever, and over time, its convenience saw it used far outside its originally intended purpose. With dataclasses now covering part of those use cases, what should one use named tuples for? In this article, I address this question, and give a few examples from real code.| death and gravity

Back in 2007 Python added Abstract Base Classes, which were intended to be used as interfaces: from abc import ABC class AbstractIterable(ABC): @abstractmethod def __iter__(self): while False: yield None def get_iterator(self): return self.__iter__() ABCs were added to strengthen the duck typing a little. If you inherited AbstractIterable, then everybody knew you had an implemented __iter__ method, and could handle that appropriately. Unsurprisingly, this idea never caught on. People instead ...| Hillel Wayne
