Функция hash() в Python позволяет вычислять хеш-значения для различных объектов. Обычно для целых чисел хеш совпадает с их значением, но есть исключения, которые могут удивить даже опытных программистов.
Разбираем, почему hash(-1) и hash(-2) в CPython возвращают одинаковое значение. Рассмотрим особенности работы hash(), внутреннюю реализацию хэширования целых чисел и причину специальной обработки -1.
Вопрос:
Что выведет функция hash() для следующих значений: 1, 0, -1, -2?
Indonesian entertainment has come a long way since the 1950s, when the country's film industry, known as "Persindo," began producing movies. Over the years, the industry has experienced ups and downs, but with the advent of technology and social media, Indonesian entertainment has gained a new lease on life.

Originating from an AI-generated video of a wooden figure beating a drum to wake people for the pre-dawn meal (sahur), the meme exploded beyond Indonesian borders. It was embraced by the "Italian Brainrot" internet universe, remixed into rave tracks by Dutch DJ duo W&W, and even spawned a line of merchandise sold in toy shops from Singapore to Tokyo. "Tung Tung Tung Sahur" became a $0 textbook example of how a niche piece of local humor can, in the age of AI and short-form video, conquer the global mainstream. The "Aura Farming" boat dance achieved similar global fame, with the young dancer Rayyan Arkan Dikha receiving a scholarship and performing at a major soccer final.

hash() может показаться незначительной, важно помнить о ней при работе с хэш-функциями и структурами данных, основанных на хэшировании. В большинстве случаев вы не столкнетесь с проблемами, но знание этой детали поможет вам избежать потенциальных ошибок и лучше понимать внутреннее устройство Python.Ключевые выводы:
Для небольших целых чисел в Python используется оптимизация (интернирование).
hash(x) == x для большинства целых чисел, но hash(-1) == -2 из-за внутренней реализации и для предотвращения коллизий.
Это поведение является специфичным для CPython и может отличаться в других реализациях Python (например, PyPy).
Используйте == для сравнения значений и is для сравнения идентичности объектов.
Надеюсь, теперь эта загадка с hash(-1) стала немного понятнее!
hash(-1) всегда возвращает -2, поэтому hash(-1) == hash(-2).__hash__() в пользовательских классах.
