Identifikatsiya operatorlari ma'lumotlarning xotira birligini aniqlash uchun ishlatiladi.
Xotira... Python xotirani hisobga olmaydi deyishadiku? CPython ob'ektlari xotirani boshqarishni optimallashtirish uchun juda ko'p xotiradan foydalanadi.Bunga misol CPython -5 dan 256 gacha bo'lgan barcha butun sonlarning global ro'yxatini saqlaydi va bularning hammasi uchun 266 * 24 = 6384 baytni oldindan ajratadi.
Ma'lumotlar turi nima u? Ma'lumotlar turiga namunalar: str satr 'salom' int butun sonlar 2 float haqiqiy sonlar 2.03 bool mantiqiy True yoki False
a = 28 b = 19 a va b o'zgaruvchi 28 va 19 ma'lumot ma'lumot turi int
a va b o'zgaruvchilar ma'lumot turi bir xil lekin xotirada joylashuvi farq qilishi mumkin. Ma'lumot xotirada joylashishini ko'rish uchun id() funktsiyasidan foydalanamiz.
is - Agar ikkala o'zgaruvchi bir xil ob'ekt bo'lsa rost (True) qaytaradi, boshqa holatda yolg'on (False) qaytaradi
print(a is b) False print(True is False) False print(False is False) True print(True is True) True
is not - Agar ikkala o'zgaruvchi bir xil ob'ekt bo'lmasa rost (True) qaytaradi, boshqa holatda yolg'on (False) qaytaradi print(a is not b) True a = 5 b = 5 print(a is not b) False

There are multiple ways you can search for Telegram channels. One of the methods is really logical and you should all know it by now. We’re talking about using Telegram’s native search option. Make sure to download Telegram from the official website or update it to the latest version, using this link. Once you’ve installed Telegram, you can simply open the app and use the search bar. Tap on the magnifier icon and search for a channel that might interest you (e.g. Marvel comics). Even though this is the easiest method for searching Telegram channels, it isn’t the best one. This method is limited because it shows you only a couple of results per search.
Export WhatsApp stickers to Telegram on Android
From the Files app, scroll down to Internal storage, and tap on WhatsApp. Once you’re there, go to Media and then WhatsApp Stickers. Don’t be surprised if you find a large number of files in that folder—it holds your personal collection of stickers and every one you’ve ever received. Even the bad ones.Tap the three dots in the top right corner of your screen to Select all. If you want to trim the fat and grab only the best of the best, this is the perfect time to do so: choose the ones you want to export by long-pressing one file to activate selection mode, and then tapping on the rest. Once you’re done, hit the Share button (that “less than”-like symbol at the top of your screen). If you have a big collection—more than 500 stickers, for example—it’s possible that nothing will happen when you tap the Share button. Be patient—your phone’s just struggling with a heavy load.On the menu that pops from the bottom of the screen, choose Telegram, and then select the chat named Saved messages. This is a chat only you can see, and it will serve as your sticker bank. Unlike WhatsApp, Telegram doesn’t store your favorite stickers in a quick-access reservoir right beside the typing field, but you’ll be able to snatch them out of your Saved messages chat and forward them to any of your Telegram contacts. This also means you won’t have a quick way to save incoming stickers like you did on WhatsApp, so you’ll have to forward them from one chat to the other.
