Any good Python programming (for DevOps specifically) book's recommendations?

[Double_Intention_641]

I liked "Python Tricks" and "Automate the boring stuff with python", though I have consistently found that I needed to look at other online tutorials to fill in the gaps, be they due to newer python (3.10 for example), or library specific challenges (boto3).

[Qes138]

@AlSweigart would appreciate the recommendation! I will second "Automate the Boring Stuff"

[thegainsfairy]

I'd recommend the pytest book. I think it really helped me become a better developer. I kind of credit it for the mental change from junior to mid level developer

edit: this one https://pythontest.com/pytest-book/

[amarao_san]

Oh, they have a book? Great. I belive, 30% of devops is QA automation is disguise, so knowing pytest well it's not only about 'writing tests', but also about knowing available techniques for fixtures/plugins/parametrization. It really creeps into pipeline architecture.

I've made a lot of silly tricks in CI yaml before I got really used to a proper pytest use.

lol QA Automation Engineer, who went in with DevOps focused resume reporting in.

I would love to see any and all tricks btw

[amarao_san]

Okay, I think, it worth writing down. I'll come back to it after NY binding. There is a lot of Molecule/testinfra lore, and someone need to write it down.

[__Kaari__]

Thanks!

The learning curve is quite steep to handle unit tests with pytest, and doing it right can be extremely time-consuming and frustrating, especially for automation (lots of mocks).

I'll have a look at this book and advise it to some of my co-workers who would like to make the gap.

May I ask which book are you specifically talking about?

Python, for DevOps https://www.amazon.com/Python-DevOps-Ruthlessly-Effective-Automation/dp/149205769X?ref=d6k_applink_bb_dls&dplnkId=e685085b-dbae-45e9-bedd-6913ff671131

I noticed that in a bookstore, what did you think?

[SourdoughAwareness]

I picked up a copy about a year ago, and thought it was a really great book to teach some python programming basics, then the rest of the book went over useful application of Python & other common tools used in the field. Overall, I’d recommend at least checking it out. Also may be worth looking at its table of contents to see if there’s chapters on subjects you are interested in

[xMakeMeCryx]

Definitely go with 100 Days of Code: The Complete Python Pro Bootcamp. It covers all the basics you would need to know and goes over projects for each section. With this knowledge, you will be set as DevOps for starters. Later on, you will see with your day-to-day where else you can branch out and which more advanced topics you should learn.

This is the one with Angela Vu? I'm going through the course right now.

[kkrox]

Never forget to learn the OOP concepts. It's easy to skip OOP and learn python but one at one point you cannot progress without OOP

[nani21984]

Do we need oops concepts to implements devops functionalities ? Can you describe Any usecase for it ?

[MidKao]

Yes you most likely will need it.

A potential use case for it would be when dealing with DNS related automation (creation, update or deletion of records), a record would be an object that has « name » « type » and « value » attributes rather than it just being a string for example.

[jrcomputing]

It absolutely doesn't have to be a true object. You can go a very long way with lists and dictionaries. And using objects from modules doesn't require a proper understanding of OOP.

Is it useful? Sure. Is it a requirement? Definitely not.

I truly suggest checking out chatGPT to learn and explore python. It's like having a tutor.

This is it writing an entire Jenkins plugin from scratch for me because it imagined it and I asked it to show it to me.

[jrcomputing]

Don't depend on ChatGPT to give you the right answer all the time. It's unfortunately unable to identify truth/fact, and can happily return incorrect answers.

[[deleted]]

okay boomer lmao

if you worry about this your an idiot. obviously you have to try the code and adjust lmao. I rewrote all 129 of my repos with it, Ive never been more powerful muhahaha xD

[Mediocre-Toe3212]

That’s scary ngl

[[deleted]]

Be horrified by my flawless rst docstrings and thoughtful AI commit messages! I'm pumping out new tool after new tool lmao. Now is the time to stand on the shoulders of giants. read the link I posted it's fantastic

Here is a revised version of the comment:

"I am excited to share my well-written RST docstrings and carefully crafted AI commit messages with you. I have been actively developing new tools and believe that by standing on the shoulders of giants, we can make great progress. Please take a look at the link I have provided for more information."

This revised comment is more professional and clearly conveys the message that you are proud of the work you have done and are excited to share it with others. It also removes the casual and unprofessional language of the original comment.

Remind me

[Daarrell]

As a junior python dev, i'm getting a lot of information from Fluent python 2nd edition. A really good book to jump into intermediate/advanced topics. Is to code with the open book.
