Что выведет этот код при запуске на Python 3.10+ (например, 3.11)?


📌 Подсказка: Подумайте о порядке проверок, о том, какие атрибуты попадают в others, и об использовании __match_args__.

Ответ:

Automatic mode
Mode manual, other keys: ['threshold', 'debug']
Low threshold 0
Краткое пояснение:

Для первого объекта (mode="auto", threshold=10) срабатывает первый case Config(mode="auto") → Automatic mode.

Для второго (mode="manual", threshold=5, debug=True) первый не совпадает, второй с threshold<5 не проходит (5 < 5 → False), зато третий case Config(mode=mode, **others) — биндинг mode='manual', остальные ключи (threshold и debug) попадают в others → Mode manual, other keys: ['threshold', 'debug'].

Для третьего (threshold=0) первый и третий не подходят (нет mode), а второй — case Config(threshold=threshold) if threshold<5 — срабатывает (0<5) → Low threshold 0.

That growth environment will include rising inflation and interest rates. Those upward shifts naturally accompany healthy growth periods as the demand for resources, products and services rise. Importantly, the Federal Reserve has laid out the rationale for not interfering with that natural growth transition.It's not exactly a fad, but there is a widespread willingness to pay up for a growth story. Classic fundamental analysis takes a back seat. Even negative earnings are ignored. In fact, positive earnings seem to be a limiting measure, producing the question, "Is that all you've got?" The preference is a vision of untold riches when the exciting story plays out as expected.

The SSE was the first modern stock exchange to open in China, with trading commencing in 1990. It has now grown to become the largest stock exchange in Asia and the third-largest in the world by market capitalization, which stood at RMB 50.6 trillion (US$7.8 trillion) as of September 2021. Stocks (both A-shares and B-shares), bonds, funds, and derivatives are traded on the exchange. The SEE has two trading boards, the Main Board and the Science and Technology Innovation Board, the latter more commonly known as the STAR Market. The Main Board mainly hosts large, well-established Chinese companies and lists both A-shares and B-shares.
