#old_content > table > tbody > tr:nth-child(4) > td.title > div > a

movies = soup.select('#old_content > table > tbody > tr')

for movie in movies:
    a = movie.select_one('td.title > div > a')
    print(a)

#old_content > table > tbody > tr:nth-child(3) > td.title > div > a
#old_content > table > tbody > tr:nth-child(4) > td.title > div > a

왜 #old_content > table > tbody > tr:nth-child(3) > td.title > div > a
#old_content > table > tbody > tr:nth-child(4) > td.title > div > a
 이 두가지 뒷부분 공통점인   td.title > div > a가   a = movie.select_one('td.title > div > a')여기에 뒷부분만 들어가는 이유와 역할 뭐죠?
 이해가 잘 안되요ㅠㅠ
