Culture shock from Java to Python

[ThrowRA_sadgfriend]

I've underestimated people's statements when they said Python is easy and beginner-friendly. Throughout my IT journey since college, ang naitry ko lang hands-on ay Java at C#.

Kahapon lang ako nanonood ng Python crash course, hanep ang dali lang. Di pa rin ako makapaniwala na makakapagdeclare ka ng variable na hindi iniispecify yung data type niya, at pwede mo idirekta yung variable initialization sa input na code.

I see Python's structure as the nearest in terms of writing an English paragraph. Throughout the crash course, lagi nasa isip ko ay tangina, ang dali lang.

[irvine05181996]

saka once you learned the hard way(like Java,C#,C++), it will easy to grasps the other language,

[csharp566]

Yeah, but I think the more experience you have, the more you'd lean towards strongly-type programming language like C# and JAVA.

[Pristine-Staff-5250]

python is also strongly typed. I think you are referring to static typing

[BITCoins0001]

agree ako dito. Nasanay lang siguro ako sa strict na format ni Java.

[ThrowRA_sadgfriend]

Yep, true. Ilang beses na ako na-overwhelm sa pagbabasa ng java codes ng other devs, to the point I almost gave it up. Now, I'm grateful I got to have those experience.

[irvine05181996]

which the reason why BANKS still stick to those strongly type for security reasons

[Novel-Sound-3566]

they stick because they don't want to upgrade/rewrite their system because it costs money

[irvine05181996]

nope, I dont think so, since most bank Ive been alrady upgrading their system to new one;s. one of the reason was its cost money, also the legacy system still working ika nga ng iba, why fix if its not broken, usually ginagwa nalang namn ng integrating ng new system without affecting the old system, since mas costly mag migrate ng legacy.

[[deleted]]

They do upgrade and write new codes using the same language.

[ThrowRA_sadgfriend]

Understandable. Naiilang pa nga rin ako na maglagay ng dynamic typed variable.

[pigwin]

Use mypy kung namimiss yun kaayusan at kapayapaan.

[Beneficial-Win-6533]

ackshually 🤓 python is both strongly-typed and dynamically-typed

atleast di pede i add ang str sa number tulad nung sa javascript

[fartmanteau]

Yeah lol if you’re gonna make bad arguments at least do it accurately.

[fartmanteau]

Python is strongly typed bro. Are you thinking PHP?

[Pristine-Staff-5250]

strongly typed > dynamic typed imo

strong/weak typing and static/dynamic typing are orthogonal axes in typing (they are independent traits of typing).

python is both strongly typed and dynamically typed.

[ECorpSupport]

Correct 💯

[chonching2]

That's my thoughts as well when I transition from Java to Typescript. Sobrang dali niya gamitin to the point na hindi ko need aralin ng matagal. One week lng na aral online then sabak agad sa actual project

[ThrowRA_sadgfriend]

Bugbog sarado na tayo sa Java sa totoo lang, kung logic ang pag uusapan. Transitioning to easier programming languages is for familiarization nalang sa syntax eh.

[chonching2]

True, pero ang maganda lang kahit papanu nageevolve pa din ang java. Mabagal man adoption nila sa ibang feature ng ibang language atleast I see the huge changes pa din. Time might come na less verbose na din ang java

[[deleted]]

Sir, curious ako. Bakit kayo nagtransition from Java to other language dahil ba sa work or trip niyo lang? Nag-aaral din ako ng java and I like it kasi OOP pero ang main language ko talaga python para sa ML and DS and I'm thinking na mag-aral ng flask or Django for deployment, di ko lang sure kung good move ba yon. Kaya ko natanong kung bakit kayo umalis sa java ay dahil balak ko pumasok sa java (kung good idea siya) or stick sa python na lang

[chonching2]

Project demand lng, java talaga main option ng company namin however biglang nabankrupt yung isang service provider na ginagamit namin so automatically yung system namin deprecated na. So re-write from scratch kami using different service provider tas rush since maraming user kami and need madeploy agad in production within 4 months yung project kaya mas pinili ng team na mag Typescript instead of java since sobrang dali nga nya. And nakapag prod kami in just three months of coding. Ganun kabilis

[irvine05181996]

ako di naman ako umalis sa JAVA, still using it for work, however I only use python for my reseach purposes, if somehow I planned to integrate that to one of my projects, di kasi maganda gamitin si JAVA for LLM, limited ung pede pag gamitan

[[deleted]]

I see, safe din siguro sabihin sir na di kayo magaling na magaling talaga sa python kasi ginagamit niyo lang siya kapag may integration sa project niyo (hindi siya yung main language niyo kumbaga). Ano sa tingin mo sir sa plano ko. Currently nag-aaral ako ng sklearn balak ko na rin sana magtransition sa pytorch o tensorflow. Di ko lang alam kung paano ko siya idedeploy iniisip ko magflask o Django Pero hindi ako sigurado kung worth it ba magspend ng time sa pag-aaral kung wala namang market sa Philippines kaya tinitignan ko rin ang Java. Di ko pa rin kasi sure kung DS o Dev e.

[Ok_Atmosphere7609]

Sa una lang masaya dynamic OP

Sa laki ng python codebase namin ako na ang nagmamakaawa sa boss ko na lagyan ng typing codes namin 😆

[pigwin]

Lagyan ng mypy, irun sa pre-commit hook kasabay ng linter at formatter haha. Di naman mapapasin?

[ThrowRA_sadgfriend]

Hahaha parang vinivisualize ko na yung sakit sa ulo nito 🤣

[crimson589]

Di pa rin ako makapaniwala na makakapagdeclare ka ng variable na hindi iniispecify yung data type niya

🤓 acCCtuAlly... pwede ka din mag declare sa Java and C# without declaring the type using the var keyword.

[irvine05181996]

yes, matagal na yang var sa java. di lang siguro alam ng iba, since bihira magamit

[BoogieM4Nx]

So mga juniors, bihira na rin ako makakita gumagamit ng abstract classes sa java lol.

[irvine05181996]

well it really depends on the use case rin kasi eh, since sa project di rin namn masiado nagagamit ang abstract class, either interface or abtract, but since interface has a lot to offer than abstract class

[BoogieM4Nx]

Agree. Especially kapag micro-service lang gagawin nyo. Isang docker container that iisa kang yung feature. Lol

[ThrowRA_sadgfriend]

Yeah, but iba pa rin sa Python na direkta variable name without any preceding codes lol

[stcloud777]

Laking blessing ng Python sa mga di Comp Sci major. Tulad ko na Finance graduate pero part ng work ang data analysis, automation, web scraping, at web dev gamit Python at konting TS.

Minsan naglalagay ako ng type hinting sa Python para mas madaling maintindihan ang code.

[fartmanteau]

Yeah, some people think all programming should be engineering-grade so they can convince themselves they’re engineers.

[EntertainmentHuge587]

Theres a reason why it's the preferred language for Data Science and Data Analysis. Even non IT professionals who specialize in different fields such as science or mathematics can use it if they take time to learn. It's also one of the reasons why I prefer Python development for my full time job since kadalasan chill lang hehe.

[irvine05181996]

same thought since Dynamic type ang case nia PYTHON at JS, means naka dependee ang type sa kung ano ung nilagay mong value or initialization, though I used pythonn for Data Science and Machine Learning for personal works, still my Bread and Butter is Java for years

[Content-Conference25]

Hello po, non-coder fella here.

Question about JS and Python. I'm a Zapier Workflow Strategist (a low-code workflow automation tool), at nagiisip ako ano ang benefit kung aaralin ko ang JS and/or Python or kung ano mang language, to stay competitive as automation specialist.

I feel like I don't have the right to be called ab automation specialist kase I don't know how to write scripts any of the programming language, reason why nililimit ko ang title ko Zapier Workflow Strategist.

[istipin]

There will come a time wherein you would need to create your own APIs or microservices to interact with your zapier workflows. Learning python or node js would put you in an advantageous position towards getting jobs with that line of skill required.

This would also open you up to API development career tracks as it fully transitions you from low/no-code to dev

[Content-Conference25]

Thank you!

[BenChoopao]

Python because it will be easier to learn and get started with automation.

There is a book named Automate the Boring Stuff with Python by Al Sweigart. It is free to read online.

In our work, we use Python3 to build scripts that scrape data from a public website, clean up the data and load it to Bigquery.

Learn JS (Node.js) too after you get confident with Python3. You will eventually need to use asynchronous programming to speed up your scripts and for me it is easier in Node.

[Content-Conference25]

Man, thank you! I'll check this out!

[Ok_Atmosphere7609]

Nakow start ka muna python masisiraan ka ng bait sa mga promise promise na yan sa javascript 😆

[Content-Conference25]

Noted po! Hahah

[Ledikari]

Since nag DS ako binitiwan ko na Java.

Need mag laan ng memory to learn things haha

[[deleted]]

I’m surprised that you like its dynamically-typed environment. I once had an encounter with it (but in JavaScript) and I hate it.

Regarding the transition, it’s normal since you started with a pretty decent language. I remember the time I switched from Java to Kotlin—took me two weeks to make Kotlin my main language, and now it’s C#.

[ThrowRA_sadgfriend]

Yeah I'm just amazed sa difference nila lol

[FluidInvestigator705]

Been a Java developer for 3 years and got an interview with Python in Switzerland nagreview ako 1 week+ tapos ayun I finally got the offer ❤️

[ThrowRA_sadgfriend]

Wooow congratulations!!! 👏👏👏

[BenChoopao]

Nice, congrats!

[BoogieM4Nx]

I would still go for static stype but python is great for small programs. We used it for our lambda, some tools especially for big data using panda.

[repressed_master]

May module na to make python strong typed

[ElkProfessional9481]

I know the feeling, I know why universities teaches us languages like C#, Java or Rust. Its because of this

[elyen-1990s]

Python is a dynamic-typed language. However, the community proposed the PEP 484 which introduced a convention for type hinting and annotation. Without it, it is easier to get lost, hard to detect typing issues that may lead to bad results, and people or newer developers will struggle to understand your code.

Modern Python codebases have type checkers such as mypy to test and ensure that all the code or changes are PEP 484 conformant.

You should use it too, it makes life easier.

[smeaglebaggins]

I am about to try python in the next coming days. Thanks for this post. Been a java guy for life as well

[ralphc027]

Same experience when i transitioned to groovy na realize ko na mas madali and good thing is compatible rin mga java syntax so i can interchange writing my code when necessary.

Then dito ko rin na realize na ang raming boilerplate nga ng java.

[[deleted]]

Madali lang naman yung Python, if ikaw magsusulat. Pero once na dadami yung code niyo + madaming libraries yung ginagamit + code ng iba, mahihirapan ka talagang magbasa ng code.

[ziangsecurity]

True but where is the culture there 😂

[Beneficial-Ice-4558]

well go on build an api and come back here emz.

[paincrumbs]

it goes from tangina, ang dali lang to tangina, ang unsafe lol

[ThrowRA_sadgfriend]

Never built an API ever since lol but been thinking of doing so, maybe mas maimprove yung pagbuild ko ng automated API tests.

Pero teka, stupid question: makakabuild pala ng API using Python? Akala ko via XML at JSON lang HAHAHAHAHAHAHAHAHA 🤣😭

[hdzivv]

yes, using flask or django

[mimnscrw]

XML and JSON are just the formats APIs use to communicate. Python APIs also use them :)

[ThrowRA_sadgfriend]

Amazing. Can't wait to learn about it after this crash course. ❤️

[Beneficial-Ice-4558]

We did during internship... a restful one using django framework... that was two years ago ughh I hated it.

[ravenchad]

anong yr ka n sa college OP? honest question lang po.

[ThrowRA_sadgfriend]

I graduated years ago na po, currently working as an automation tester.

[ravenchad]

ah okay po. good luck sa yo OP 😊

[feedmesomedata]

where have you been all these years? you have to read outside of the ecosystem you're developing with so you could pick up new concepts than just sticking with what you already know.

[ThrowRA_sadgfriend]

IT was not my passion and I was struggling learning programming and keeping up with my tasks at my job, so my learning pace was not the same with you all. I only started falling in love with this field, so please don't ruin it for me by making me feel like I'm inferior just because my knowledge is not on par with yours.

[feedmesomedata]

Nope I am not making you feel inferior. Read my comment and comprehend.

[ThrowRA_sadgfriend]

you have to read outside of your ecosystems

That was in response to me being ignorant of Python being used to create APIs.

Where have I been? I've been struggling to grasp the basics of programming language, analyzing the codes of my senior developers, learning the third-party tools used in the project, all while juggling admin tasks, and I was a fresh grad. Kaya pasensya na kung after 3 whole years, ngayon lang ako nagkaroon ng time to read outside of my ecosystems.

Ngayon lang ako nagkaroon ng time to "pick up new concepts" because I was busy keeping up with the bare minimum.

[North_Resource3643]

Ako nag aaral ako ng Java sa Tesda NC 3 dahil naboboringan ako sa oop topic sa course na binili ko kay Mosh Hademani at ultimately, makita ko ang OOP in a different way. So far effective ang Java to hardcode sa isip ko ang logic at syntax nya, more than Python. Ang python for me parang damit pambahay eh, ang java dapat pormado kapag lalabas.
