И теперь ее гораздо проще менять, оптимизировать и проводить эксперименты.
В качестве примера, можно посмотреть на попытку добавления register-based интерпретатора. Другой пример, что часто два опкода идут вместе и выполняются последовательно большую часть времени. Например,
LOAD_CONSTи RETURN_VALUE. Для оптимизации, можно добавить новый опкод этой операции. Вместо двух действий он будет выполнять одно. На частых задачах получится неплохая прибавка к производительности. Еще один пример: опкод
CALL_FUNCTION.Сам по себе довольно медленный. У него есть целая семья оптимизаций, например специализация CALL_FUNCTION_ISINSTANCE, когда мы выкидываем промежуточный слой и сразу вызываем C-реализацию isinstance. Минус в том, что Python богатый и динамически типизированный язык. В runtime может что-то поменяться и мы получим замедление — придется сваливаться обратно на общий путь опкода CALL_FUNCTION.Читать: https://habr.com/ru/articles/717420/

Как изучать язык Python для веб-разработки в 2023 году. Общие ориентиры
Привет, Хабр! Меня зовут Тимофей, я Python Engineer с опытом в 3+ года.
Я бы не назвал данную статью полноценным роадмэпом в том понимании, в котором это слово обычно используют. В статье нет сроков изучения, отсутствует подробный план, затрагивающей все темы и подтемы. Да и зачем нужен еще один роадмэп «под копирку», когда в сети и так хватает качественных предложений.
Скорее, я хотел бы составить абстрактный план обучения, который сможет задать общий ориентир, а также будет коррелировать с роадмэпом вроде roadmap.sh. Кроме этого, я смогу дать несколько полезных советов из своего опыта, а также составлю списки полезных ресурсов для изучения языка, сопутствующих инструментов и технологий, которые в свое время помогли или же помогают мне самому.
