Цикл в RegEx для поиска подстрок с условием

Я хочу поделиться своим изобретением, которое позволяет вам использовать только одно регулярное выражение, которое будет искать подстроку в строке с определенным условием. Если хотите, называйте это циклом в RegEx, которого раньше не существовало! Я поделюсь с вами не только разными полезными шаблонами, но и покажу различные примеры от простых до сложных.

I just realized that `in` doing #substring search on strings in #Python is actually a convenience feature (that violates the pure nature of iterating over iterables).

Took me only 24 years to understand. Because Python is #intuitive, not #dogmatic. Made for humans.
