我怎样才能使它更快？很多数组

Question

我想使速度更快，我不是一个优秀的编码人员，只想学习。该程序读取以逗号分隔的普通艺术家的段落。用户输入所需艺术家的姓名，程序搜索段落以查找所有相关艺术家，并将它们按最常见到最不常见的顺序排序。艺术家的文本文件很大，只有600kb的文本，所以也许这就是它缓慢的原因。

class ArtistSuggester:
fileName = "list_of_artists.txt"
arrayOfLists = []
artist = input("Enter Artist Name: ")


@classmethod
def make_array(cls):
    # sets text to 2D-array
    f = open(cls.fileName, 'r', encoding="utf8")
    curr_par = f.read().split("\n")
    for line in curr_par:
        cls.arrayOfLists.append(line.split(","))

@classmethod
def get_locations(cls):
    # searches array for given artist and returns array with areas where the artist was found
    locations = []
    for x in range(0, len(cls.arrayOfLists)):
        for y in range(0, len(cls.arrayOfLists[x])):
            if cls.arrayOfLists[x][y] == cls.artist:
                locations.append(x)
    return locations

@staticmethod
def search_array_for_artist(the_list, artist):
    # searches given array for the given artist's name and returns the position
    # if found nothing returns negative number to symbolize non-existence
    pos = 0
    for x in range(0, len(the_list)):
        if the_list[x] == artist:
            pos = x
            break
        else:
            pos = -1
    return pos

@classmethod
def ordered_suggestion_list(cls):
    # makes the final suggestion list in correct order
    # makes two arrays, one with the names and the other with the counts of each throughout the text file.
    check = cls.get_locations()
    final_list = cls.arrayOfLists[check[0]]
    final_list.remove(cls.artist)
    count = [1] * int(len(final_list))
    for x in range(1, len(check)):
        for y in range(0, len(cls.arrayOfLists[check[x]])):
            if cls.arrayOfLists[check[x]][y] == cls.artist:
                continue
            elif cls.search_array_for_artist(final_list, cls.arrayOfLists[check[x]][y]) > 0:
                count[cls.search_array_for_artist(final_list, cls.arrayOfLists[check[x]][y])] += 1
            else:
                final_list.append(cls.arrayOfLists[check[x]][y])
                count.append(1)
    # makes a dict based off the count and names list to combine values to the keys
    combined_list = dict(zip(final_list, count))
    new_list = []
    for key, value in sorted(combined_list.items(), key=lambda x: x[1], reverse=True):
        new_list.append(key)
    print(new_list)
