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')

Kalit: python Qiymat: django
Kalit: javascript Qiymat: react
Kalit: php Qiymat: laravel

Look for Channels Online

You guessed it – the internet is your friend. A good place to start looking for Telegram channels is Reddit. This is one of the biggest sites on the internet, with millions of communities, including those from Telegram.Then, you can search one of the many dedicated websites for Telegram channel searching. One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels. If you want to join a private channel, you’ll have to ask one of its members to invite you.

The lead from Wall Street offers little clarity as the major averages opened lower on Friday and then bounced back and forth across the unchanged line, finally finishing mixed and little changed.The Dow added 33.18 points or 0.10 percent to finish at 34,798.00, while the NASDAQ eased 4.54 points or 0.03 percent to close at 15,047.70 and the S&P 500 rose 6.50 points or 0.15 percent to end at 4,455.48. For the week, the Dow rose 0.6 percent, the NASDAQ added 0.1 percent and the S&P gained 0.5 percent.The lackluster performance on Wall Street came on uncertainty about the outlook for the markets following recent volatility.
