Сравнение списка со строкой и печать совпадающей строки списка в строке

1 голос
/ 08 октября 2019

Я пытаюсь сравнить список с текстом строк и вывести строку, соответствующую элементу в списке

Я пробовал приведенный ниже код, но получаю строки, IP-адрес которых отсутствует в списке

Вы можете использовать регулярное выражение, чтобы гарантировать, что IP-адреса совпадают только в строке, если они не предшествуют или сопровождаются какими-либо дополнительными точками или цифрами.

Если формат постоянен, вы можете искать каждый ip (с пробелами до и после), в каждой строке или использовать регулярное выражение.
