圖片壓縮的太厲害了，看不清楚，代碼如下：

with open('movies.csv', 'r') as f:

reader = csv.reader(f)

texts = list(reader)

#print(texts[:3])

#import sys; sys.exit(0)

with codecs.open('output.txt','utf_8_sig') as f:

music_zone = {}

sex_zone = {}

family_zone = {}

list_music = []

list_sex = []

list_family = []

for title, score, region, cate,*_ in texts:

if cate == "音樂":

list_music.append(region)

elif cate == "情色":

list_sex.append(region)

elif cate == "家庭":

list_family.append(region)

else:

pass

for region in list_music:

if region in music_zone:

music_zone[region] += 1

else:

music_zone[region] = 1

top3_music = sorted(music_zone.items(), key=lambda x: x[1], reverse=True)[:3]

n_movies_of_music = sum(music_zone.values())

music_result = '音樂類別中排名前三的地區分別為{}'.format(['{},({:.2%})'.format(region, cnt/n_movies_of_music) for region, cnt in top3_music])

for region in list_sex:

if region in sex_zone:

sex_zone[region] += 1

else:

sex_zone[region] = 1

top3_sex = sorted(sex_zone.items(), key=lambda x: x[1], reverse=True)[:3]

n_movies_of_sex = sum(sex_zone.values())

sex_result = '情色類別中排名前三的地區分別為{}'.format(['{}({:.2%})'.format(region, cnt/n_movies_of_sex) for region, cnt in top3_sex])

for region in list_family:

if region in family_zone:

family_zone[region] += 1

else:

family_zone[region] = 1

top3_family = sorted(family_zone.items(), key=lambda x: x[1], reverse=True)[:3]

n_movies_of_family = sum(family_zone.values())

family_result = '家庭類別中排名前三的地區分別為{}'.format(['{}({:.2%})'.format(region, cnt/n_movies_of_family) for region, cnt in top3_family])

f.write( music_result + "\n" + sex_result + "\n" + family_result)
