Заметка начинающим, которые часто сталкиваются с подобной непоняткой. Ситуация следующая, есть список файлов: names = [ 'image.bmp', 'second.txt.bkp', 'data.db', '.config.cfg', 'file.ext.bkp' ] И мы хотим убрать у них окончание ".bkp". Не знаю зачем, пример довольно надуманный) Но суть он показывает, а это главное. Те, кто еще не очень знаком с библиотекой os.path или pathlib, вероятно решат обработать имена как строки. И тут вполне подойдет метод строки strip(). Что делает этот метод? Он отрезает указанные символы по обеим сторонам строки. Если ничего не указать, то убирает невидимые символы (пробелы, табуляции и переносы строк). В нашем случае будет выглядеть вот так: >>> name.strip('.bkp') То есть просим удалить строку '.bkp' по краям имени файла, если таковая есть. Можно применить аналогичный метод rstrip(), чтобы отрезать только справа, но для этого примера используем обычный. >>> for name in names: >>> print(name.strip('.bkp')) image.bm second.txt data.d config.cfg file.ext Хм, что-то не то с нашими именами! Что случилось??? Видим нежелательное переименование в именах, где и близко не было указанной строки '.bkp' А дело всё в том, что данный метод ищет не указанную строку, а указанные символы, и не важно в каком порядке. Для метода strip() строка '.bkp' это не паттерн для поискаа список символов. Потому он отрезал симовол 'p' от '.bmp' и удалил точку из файла '.config.cfg'. Как тогда правильно заменить именно паттерн? Для начинающего можно посоветовать метод строки replace(), который как раз использует для замены указанную строку целиком. В нашем примере заменим её на пустую строку. >>> for name in names: >>> print(name.replace('.bkp', '')) image.bmp second.txt data.db .config.cfg file.ext Уже лучше, но помните, это лишь пример про strip(). Для работы с именами файлов есть способы и более "правильные", дающие однозначно верный результат. Я взял файлы только в качестве примера. Даже replase() тут может сделать не то что ожидаем. Просто впредь будьте внимательны с этим strip(). #basic
