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…

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')

Should You Buy Bitcoin?

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.

A Telegram spokesman declined to comment on the bond issue or the amount of the debt the company has due. The spokesman said Telegram’s equipment and bandwidth costs are growing because it has consistently posted more than 40% year-to-year growth in users.
