I'm working on a class search program, so please give me some advice

class stat:
    def __init__(self, line):
        self.genre = line[1]
        self.member = line[2]
        self.album = line[3]
        self.like = int(line[6])
        self.stat = []
        self.total = 0

    def like_sub(self.line):
        a = stat(self, line)
        self.stat.append(a)
        self.total += a.get_subtotals()


    def genre_stat(self):
        for a in self.genre:
            a.print()
        print(f'{self.genre} \n{self.like}') 
    def member_stat(self):
        a = 0
        return a + self.like
        print(a)

    def album_stat(self):
        a = 0
        return a + self.like
        print(a)



def bts_list(filename):
    with open(filename, encoding = 'UTF-8') as f:
        slist = [stat(line.split(',')) for line in f]
    return slist


btslist = bts_list('bts.txt')

def stat_genre():
    for s in btslist:
        s.genre_stat()

def stat_album():
    for s in btslist:
        s.album_stat

def stat_member():
    for s in btslist:
        s.album_stat
