Итак, я получил свою программу до такой степени, что она должным образом отделяет строки текстового файла и может даже соответствовать шаблону для первой строки текста, но мне также необходимо иметь возможность обнаружить и отделить адресные строки текстового файла и сортировать их в зависимости от их направления или улицы/Бродвей, но я даже не могу определить начальный шаблон для установки адреса. Я использую regex неправильно, и поэтому адресная часть не будет обнаружена должным образом? < /p>

Below is the lines of code that should be able to process the address lines but for some reason it wont match the pattern and the outputs which properly separate the address lines and can be seen in the print statement above the for loop dealing with the addresses but for some reason the address lines arent even being detected as matches and im confused as to why that is.
