Python's two modules for random numbers
* random - psevdo random qiymatlar uchun, MT(Mersenne Twister)dan foydalanib ketma-ketlik yasaladi.
* secrets - "haqiqiy" random qiymatlar uchun, kriptografik amallarda ham foydalanish mumkin(ko'proq shu yerda o'zi).
2 ta alohida kutubxonaga ajratilgani biroz yoqmaydi o'zimga ham, secrets nomi ham g'alati - mavjud public funksiyalari tasodifiy son/token generatsiyasi uchun faqat, kriptografiya/"sekretlarga" to'g'ridan-to'g'ri aloqasi yo'q ..."There should be one-- and preferably only one --obvious way to do it" To'liq: https://lwn.net/Articles/1097468 (qiziq) @AbduazizPy
| 2 |  @AbduazizPy | 330 |
| 3 | Python 3.15.0!
Qiziq(balkim): texnik intervyuda, nomzodlardan Pythonning qaysi versiyasi ishlatayotgani so'rayman - javob olmadim so'ngi vaqtlarda. Niyatim keyingi savollarni shunga "to'g'irlash". Rostdan ham kod yozishmayapdi(yoki umuman qiziq emas), umid qilamanki Pythonni o'rnatishni bilishadi.
+ Yangi sentinel built-in turi qo'shildi. Endi bu kabi bosh og'riqlarga hojat yo'q. O'rniga:
UNINITIALIZED = sentinel("UNINITIALIZED")
+ Unpacking in comprehensions - negadur comprehensionlar ichida qilib bo'lmas edi unpackingni(*x, **x). Endi mumkin, masalan list:
lists = [[1, 2], [3, 4], [5]]
# [x for L in lists for x in L] ning o'rniga:
[*L for L in lists]
# [1, 2, 3, 4, 5]
+ Lazy importlar - ba'zi importlarni kechiktirib, loyihani ishga tushish vaqtini tezlatish mumkin. Masalan, Djangodan foydalanganda bunga ehtiyoj bor - loyihangizda import vaqtlarini tahlil qilib, lazy kalit so'zi(soft)ni qo'yib, bahramand bo'lish mumkin.
lazy import suni_intele
(sinab ko'rsangiz, izohlarda yozing)
+ frozendict - @AbduazizPy/383
+ Tachyon(profiling.sampling) - yangi profiler, qulay, tezroq & aniqroq. Pyinstrumentdan foydalanaman, sezilarli overhead bor, ammo Tachyon'da vaziyat boshqacha. Kodni o'zgartirishingizga to'g'ri kelmaydi profiling uchun, loyiha productionda ishlab turganida ham foydalanish mumkin.
+ Eksperimental JIT yanada yaxshiroq & nisbatan tezroq. Lekin, hozirda aktiv ish to'xtatilgan - PEP kutilyapdi[1][2].

| 9 |  Sog'lom odamlar hammasi tasavvurga ega, "osh haqida o'ylamang" desam, baribir oshni rasmi hayolingizga ... Qaysiki tasavvur tushunchasi fanda mental image deb yuritiladi. U miyamizning ko'zi. Ammo, Aphantasia bilan og'riganlarda bu kabi "rasmchalar" paydo bo'lmaydi miyada, afsus.
Haftalik kalendar/jadval haqida tasavvur qilganda, hayolimga Microsoft Teams(uzur, MS Trash)dagi kalendar emas, maktab davridagi kundalik sahifasi men eng ko'p ko'radigan rasm. Boshqacha o'ylashga harakat qilganman, foydasi yo'q.
Har-xil uslublarda kalendar yuritib ko'rdim(TODOlardan tashqari), hech biri intuitiv tuyulmadi - kundalik rasmi hayolda baribir. Ko'rinishidan optimal, ishlatib ko'raychi.
Sahifani tashkillashtirish bo'yicha takliflar bo'lsa izohlarda qoldiramiz.

| 10 | frozendict
frozendict CPython'ning 3.15-talqinida yangi built-in ma'lumot turi sifatida qo'shildi.
https://peps.python.org/pep-0814
Ichki detallarini hisobga olmasak, foydalanilishi jihatidan(m: metodlar, tashqi amallar) biz bilgan standart dict'dan farqi yo'q. Tuzlishi har doimgidek { key: value } tarzda, yaratilgandan keyin o'zgartirib bo'lmaydi (immutable). Xuddi tuple'dagi kabi immutability xossasi obyektning o'ziga nisbatan aytilyapdi [1]. Uning ichidagi qiymatlari(value) mutable bo'lishi mumkin (m: list).
Ammo ular ham immutable bo'lsa, demak biz to'liq immutable dictionary'ga ega bo'lamiz. Demak uni keyin o'zini heshlashimiz ham mumkin(hashability), qaysiki biz bilgan standart dict holatida unday emas.
Heshlab "bilishimiz"[2] bizga frozendictni boshqa dictlar uchun ham kalit(key) sifatida foydalanish imkonini ham beradi. PEPda aytilganidek frozendict "mutable default argument" muammosini ham bilvosita hal qiladi [3].
Parallel/concurrent dasturlar yozayotganingizda, bir qiymat - bir qancha protsess/thread/korutinlar o'rtasida "share" qilinishiga zarur bo'ladi. Bunda ushbu qiymat mutable bo'lsa bizda har xil muammolar tug'diradi (m: siz xohlamagan tarzda uni boshqa joydan o'zgartirilsa). Bunda frozendict standart dictga nisbatan "share" qilish uchun eng yaxshi nomzod.
Bu g'oya avval ham taklif etilgan, ammo hozir bizda avvalgidan ko'ra ko'proq "use case"lar mavjud: asyncio, free-threading hamda subinterpreters. Shu tufayli ushbu urinish muvaffaqiyatli kechdi.
To'liq tafsilotlar bilan PEPda tanishib chiqishingiz mumkin.
[1] Aniqroq aytsak - "shallow immutability".

| 12 | 996
written on September 04, 2025 (by Armin Ronacher)
“Amazing salary, hackerhouse in SF, crazy equity. 996. Our mission is OSS.” - Gregor Zunic
“The current vibe is no drinking, no drugs, 9-9-6, […].” - Daksh Gupta
“The truth is, China’s really doing ‘007’ now—midnight to midnight, seven days a week […] if you want to build a $10 billion company, you have to work seven days a week.” - Harry Stebbings
I love work. I love working late nights, hacking on things. This week I didn’t go to sleep before midnight once. And yet…
I also love my wife and kids. I love long walks, contemplating life over good coffee, and deep, meaningful conversations. None of this would be possible if my life was defined by 12 hour days, six days a week. More importantly, a successful company is not a sprint, it’s a marathon.
And this is when this is your own company! When you devote 72 hours a week to someone else’s startup, you need to really think about that arrangement a few times. I find it highly irresponsible for a founder to promote that model. As a founder, you are not an employee, and your risks and leverage are fundamentally different.
I will always advocate for putting the time in because it is what brought me happiness. Intensity, and giving a shit about what I’m doing, will always matter to me. But you don’t measure that by the energy you put in, or the hours you’re sitting in the office, but the output you produce. Burning out on twelve-hour days, six days a week, has no prize at the end. It’s unsustainable, it shouldn’t be the standard and it sure as hell should not be seen as a positive sign of a company.
I’ve pulled many all-nighters, and I’ve enjoyed them. I still do. But they’re enjoyable in the right context, for the right reasons, and when that is a completely personal choice, not the basis of company culture.
And that all-nighter? It comes with a fucked up and unproductive morning the day after.
When someone promotes a 996 work culture, we should push back.

Fikr bildirishingiz mumkin, iloji boricha python o'ziga ko'proq oid bo'lgani hamda o'ta "general"(umumiy, ya'ni "Python va AI" kabi) bo'lmagani yaxshiroq.

| 20 | PEP-0765: finally ichidagi return
Quyidagi holat tanishmi?
>>> def bool_return() -> bool:
... try:
... return True
... finally:
... return False
...
>>> bool_return()
False # 🙂↔️
Python bo'yicha texnik intervyularda so'raladi, "bu False qaytaradi" degan javob kutiladi. Ammo, True desangiz "finally qanday ishlashini bilmas ekansiz" deyiladi.
Dokumentatsiya bo'yicha qaralganda, exception handlingda finally har qanday holatda eng oxirgi bo'lib bajariladigan blok sanaladi. Shu sababli, undagi return yuqori ustunlikka ega (oxirgi bo'lgani uchun):
The return value of a function is determined by the last return statement executed. Since the finally clause always executes, a return statement executed in the finally clause will always be the last one executed. [1]
Bu holatni qabul qilish men uchun qiyin bo'lgan. Funksiyani chaqiramiz, chaqirilgan funksiya(routine) return orqali o'z vazifasini yakunlaydi, va "return adres" tomon sakraydi(qaytadi) ya'ni avval chaqirilgan joyiga [2]. Fundamental tushuncha, shunday emasmi !? Nega 1-returnning e'tiborsiz qoldirilayotgani g'alati va yoqimsiz. Dokumentatsiyada yozilgani, yoki kimdir aytgani uchun buni shundayligicha qabul qilishimiz kerakmi ... ?
finally bloki "cleanup"(tozalash) ishlarida foydalaniladi deb ta'kidlangan, va sog'lom intelekt uni shu uchun ishlatadi. Yuqoridagiga o'xshash kodlar sababli tushunarsiz xatoliklar keltirib chiqaradi.
Keyinroq bildimki, bu pythondagi nozik mavzulardan biri ekan )
Eng oson yechim, dasturchiga buni yozgani qo'ymaslik & o'rgatish. Linterlar tomonidan bunga qarshi choralar ko'rilgan[3][4][5], interpretator tomonidan esa yo'q. Avvalgi urinishlar rad etilgan [6]. Yaqin o'tmishda bu mavzu qayta ko'tarildi (PEP-0765), va ushbu "xatolik" hal qilindi (deyarli).
Men shunchaki returnga oid holatni ozgina yoritdim, aslida break/continue bilan bog'liq drama ham bor va ular bilan PEP orqali tanishib chiqishingiz mumkin.
Yangi interpretator (3.14dan boshlab), ushbu holat uchun SyntaxWarning generatsiya qila boshlaydi (ogohlantirish, ya'ni kodni to'xtamaydi, sizni xabardor qiladi). Keyingi relizlarda SyntaxError chaqirilishi ta'kidlanmoqda.
