Python keywords make up the fundamental building blocks of any Python program. In this video course, you’ll learn the basic syntax and usage for each of Python’s thirty-five keywords so you can write more efficient and readable code.




It isn’t much fun creating your own desktop applications if you can’t share them with other people: learn how to turn your PyQt6 application into a distributable installer for Windows using PyInstaller and InstallForge.


嗯哼? win11 ? 祝你好运...

...Using frameworks is a must. Writing maintainable code is a must.

DevOps - you'll quickly run into requirements to write parallel work. Not using something like fabric is a waste of your employer's money hiring you. You'll quickly run into requirements to use ansible/terraform/other. Same applies here; surrounding tools with subprocess and parsing stdout/stderr is a waste of your employer's money. Use appropriate packages, instead.

DataScience - all the cool toys, from simple stuff like pandas, or more focused ones like working with spark and the plethora of big data libraries require indepth knowledge of both the library and the underlying datastore. Combined, you make the most of your time and hardware. Not doing so, and only writing something that works on a small scale is a common costly mistake.

Security - python is just a helper tool. Your requirements, depending on position, will be focal knowledge about a domain and its set of tools. From highly skilled domains like research onward to threat hunting, PT and to the entry level stuff like NOC.

You're better off enjoying the little wins in life and dealing with the less pleasant moments. That'll give you a nice career in anything you choose.



Articles, Tutorials and Talks

PyPy is a popular alternative implementation of Python and with a project of this size testing is always a challenge. This blog post highlights the testing philosophy used at PyPy, how the tests are organized, and how they avoid performance regressions.




In this tutorial, you’ll learn how to use a Python virtual environment to manage your Python projects. You’ll also dive deep into the structure of virtual environments built using the venv module, as well as the reasoning behind using virtual environments.



这一点儿也不Primer... 其实, Py 运行时, 最困难的并不是合理分离, 而是, 快速部署以及迁移复用


“I wanted to make a physics simulation 100x faster. I got it 4x faster exercising my best NumPy skills, and 50x faster after rewriting in Rust with a couple of other optimizations. I’d probably get to 100x if I had more than 2 cores.”


优化其实很容易上瘾, 不过, 更加容易忘记, 这得是业务足够稳定, 不提高性能就亏的场景中, 才合理...
