Testlarni guruhlarga ulashing! 🗓MUNDARIJA: --------------------------- ⭕️ 1-bo'lim “Asosiy tushunchalar” Ⓜ️ Python nima? Ⓜ️ Birinchi dastur Ⓜ️ Oddiy operatsiyalar Ⓜ️ Haqiqiy sonlar Ⓜ️ Matnlar (strings) Ⓜ️ O'zgaruvchilar (Variables) Ⓜ️ Ma'lumotlarni olish…
Ⓜ️ *args va ** kwargs

Funksiya chaqirilganda argumentlar soni teng bo'lmasa TypeError xatoligini qaytaradi.


def func(argument1, argument2, argument3):
print(argument1 * argument2 + argument3)


func(2, 6)

TypeError: func() missing 1 required positional argument: 'argument3'


Funksiyalarda o'zgaruvchan miqdordagi argumentlarni uzatish uchun maxsus belgilardan *, ** foydalaniladi.

*args (kalit-qiymatsiz argumentlar)
**kwargs (kalit-qiymatli argumentlar)

args va kwargs shunchaki argumentlar ro'yxatiga berilgan nom.Bu nomni boshqa istalgan nomga o'zgartirishingiz mumkin.
Masalan: *kalitsiz va **kalitli. Lekin dastur biror jamoa tomonidan yoziladigan bo'lsa yoki dastur kodi sotilishi rejalashtirilgan bo'lsa argumentlar roʻyxatini args va kwargs kabi nomlash maqsadga muvofiqdir.

Argsga misol:

def func(arg1, *arg):
print('Birinchi argument: ' + arg1)
for i in arg:
print('Boshqa argument: ' + i)


func('@pythonuz', '@js_uz', '@phpuz', '@pyqt5')


Birinchi argument: @pythonuz
Boshqa argument: @js_uz
Boshqa argument: @phpuz
Boshqa argument: @pyqt5


Kwargsga misol:


def func(**kwarg):
for x, y in kwarg.items():
print('Kalit: ' + x, ' Qiymat: ' + y)


func(python='django', javascript='react', php='laravel')

How to Use Bitcoin?

n the U.S. people generally use Bitcoin as an alternative investment, helping diversify a portfolio apart from stocks and bonds. You can also use Bitcoin to make purchases, but the number of vendors that accept the cryptocurrency is still limited. Big companies that accept Bitcoin include Overstock, AT&T and Twitch. You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”

Telegram Auto-Delete Messages in Any Chat

Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.
