Python Decorators: The Complete Guide

Python decorators are a great way to add functionality to your Python functions. In this video, I'll show you what they are, how they work, and some of the most useful decorators you can use in your code.

Faster or Slower? Performance Mystery of Python Idioms Unveiled with Empirical Evidence
In the paper, we create a large synthetic dataset with 24,126 pairs of non-idiomatic and functionally-equivalent idiomatic code for the nine unique Python idioms identified in Zhang et al., and reuse a large real-project dataset of 54,879 such code pairs provided by Zhang et al. We develop a reliable performance measurement method to compare the speedup or slowdown by idiomatic code against non-idiomatic counterpart, and analyze the performance discrepancies between the synthetic and real-project code, the relationships between code features and performance changes, and the root causes of performance changes at the bytecode level. We summarize our findings as some actionable suggestions for using Python idioms.

Efficient DevSecOps workflows: Hands-on python-gitlab API automation
In this blog post, you will learn about the basic usage of the library by working with API objects, attributes, pagination and resultsets, and dive into more concrete use cases collecting data, printing summaries and writing data to the API to create comments and commits.

Accelerating Python Applications with cuNumeric and Legate
This post provides an introduction to cuNumeric, an endeavoring drop-in replacement for NumPy based on the Legion programming system. It transparently accelerates and distributes NumPy programs to machines of any scale and capability, typically by changing a single module import statement. cuNumeric achieves this by translating the NumPy application interface into the Legate programming model and leveraging the performance and scalability of the Legion runtime.
