Error 'int' object is not subscriptable, How do i convert it to list?

Question

I am new to python, I have this code:

# columns are [0]title [1]year [2]rating [3]length(min) [4]genre [5]budget($mil) [6]box_office_gross($mil)

oscar_data = [

    ["The Shape of Water", 2017, 6.914, 123, ['sci-fi', 'drama'], 19.4, 195.243464],

    ["Moonlight", 2016, 6.151, 110, ['drama'], 1.5, 65.046687],

    ["Spotlight", 2015, 7.489, 129, ['drama', 'crime', 'history'], 20.0, 88.346473],

    ["Birdman", 2014, 7.604, 119, ['drama', 'comedy'], 18.0, 103.215094]

]

def filter_by_genre(data, genre):

    result = []

    for row in data:

        genres = row[4]

        if genre in genres:

            result.append(row)

    return result

all_genres = [

    'sci-fi', 'drama', 'crime', 'history', 'comedy', 'biography',

    'thriller', 'war', 'melodrama', 'action', 'adventure', 'western',

    'mystery', 'horror'

]

genres_counts = []

for genre in all_genres:

    count = len(filter_by_genre(oscar_data, genre))

    genres_counts.append(genre)

    genres_counts.append(count)

print('Genre        | Number')

print('------------------------')

for row in genres_counts:

    genre = row[0]

print('------------------------')

for row in genres_counts:

    genre = row[0]

    count = row[1]

    print('{: <11} | {: >10}'.format(genre, count))

I have made my list shorter for the sake of the post, It supposed to count each genre in oscar_data and print it with the genre and the count.

But I am getting the below error

  File "temp.py", line 63, in <module>

    genre = row[0]

TypeError: 'int' object is not subscriptable

What am I supposed to do to make that int into a list? row[1]

    print('{: <11} | {: >10}'.format(genre, count))

Answer 1

Your error is been introduced here:

genres_counts.append(genre)

genres_counts.append(count)

You  have append genre and count as separate values, not as the collection. Replace those two lines with:

genres_counts.append((genre, count))

Better yet, use list comprehension:

genres_counts = [(genre, len(filter_by_genre(oscar_data, genre))  

                 for genre in all_genres]
