⭕️ 2-bo'lim “Operatorlar” ————————————— Ⓜ️Operatorlar guruhlari? ----------------------------- Pythonda operatorlar quyidagi guruhga bo'linadi. Arifmetik operatorlar Tayinlash operatorlari Taqqoslash operatorlari Mantiqiy operatorlar Identifikatsiya operatorlari…
Ⓜ️ A'zolik operatorlari
A'zolik operatorlari ob'ektda ketma-ketlik mavjudligini tekshirish uchun ishlatiladi:

satr =  'salom dunyo 22'
list = ['salom dunyo', 'hello world', 22, '33']

in Ob'ektda belgilangan ketma-ketlikda o'zgaruvchini topsa rost (True) qaytaradi, boshqa holatda yolg'on (False) qaytaradi.

print('salom' in satr) True
print('salom' in list) False
print('salom dunyo' in list) True
print(22 in satr) Error
print(33 in list) False

not in Ob'ektda belgilangan ketma-ketlikda o'zgaruvchini topmasa rost (True) qaytaradi, boshqa holatda yolg'on (False) qaytaradi.

print('hello' not in satr) True
print('salom' not in list) True
print('salom dunyo' not in list) False
print(22 not in list) False

Should I buy bitcoin?

“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.

If riding a bucking bronco is your idea of fun, you’re going to love what the stock market has in store. Consider this past week’s ride a preview.The week’s action didn’t look like much, if you didn’t know better. The Dow Jones Industrial Average rose 213.12 points or 0.6%, while the S&P 500 advanced 0.5%, and the Nasdaq Composite ended little changed.
