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().

Geopolitical questions rarely move markets when they become obvious.
They move when probability starts shifting before formal signals appear.
That is why prediction systems matter.
Not because they claim certainty, but because they surface how conviction changes while narratives are still forming.
At EdgeMarket, we study how distributed judgement reacts to emerging geopolitical scenarios long before consensus hardens.
The important signal is rarely the headline itself.
It is how probability changes before the headline arrives.
