🔥 Enum в Python: красиво описываем константы

Хватит писать вот это:
STATUS_OK = 1
STATUS_ERROR = 2
STATUS_PENDING = 3


Лучше так:

from enum import Enum

class Status(Enum):
OK = 1
ERROR = 2
PENDING = 3


➡️ Зачем вообще Enum

🔵 Код становится читаемее
if status == Status.OK: читается в 100 раз понятнее, чем if status == 1:

🔵 Защита от ошибок
Enum не даст случайно передать в функцию что-то несуществующее.

🔵 Возможность красиво выводить

print(Status.OK.name)   # OK
print(Status.OK.value) # 1


🔵 Сравнение работает как надо


if status == Status.ERROR:

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.

What Is Bitcoin?

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
