...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.

• 叕一个优化故事
  • ZACH MITCHELL

“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...

不觉中蟒周刊快译已经到了第10个年头

去年开始有小伙伴加入承担 pythonisa 周刊的翻译, 从来没提醒过, 可就这么默默坚持下来了...

问为什么:

[皱眉]每周新闻资讯 怎么能错过 
看看有什么新东西 
当有新的发现时：
    what f**k 还能这样玩？ 还有这东西？
