IMDBpy - Get Genres from the Top 20 movies

I'm trying to extracting a dataset with the top 20 movies and each genres and actors. For that I'm trying with the following code:

top250 = ia.get_top250_movies()
limit = 20;
index = 0;
output = []
for item in top250:
    for genre in top250['genres']:
        index += 1;
        if index <= limit:
            print(item['long imdb canonical title'], ": ", genre);
        else:
            break;

I'm getting the following error:

Traceback (most recent call last):
  File "C:/Users/avilares/PycharmProjects/IMDB/IMDB.py", line 21, in <module>
    for genre in top250['genres']:
TypeError: list indices must be integers or slices, not str

I think the object top250 don't have the content genres...

Anyone know how to identify each genre of each movies?

Many thanks!

Solution

From the IMDbPY docs:

"It’s possible to retrieve the list of top 250 and bottom 100 movies:"

>>> top = ia.get_top250_movies()
>>> top[0]
<Movie id:0111161[http] title:_The Shawshank Redemption (1994)_>
>>> bottom = ia.get_bottom100_movies()
>>> bottom[0]
<Movie id:4458206[http] title:_Code Name: K.O.Z. (2015)_>

get_top_250_movies() returns a list, thus you can't access the movie's genre directly.

Here's a solution:

# Iterate through the movies in the top 250
for topmovie in top250:
    # First, retrieve the movie object using its ID
    movie = ia.get_movie(topmovie.movieID)
    # Print the movie's genres
    for genre in movie['genres']:
        print(genre)

Full working code:

import imdb

ia = imdb.IMDb()
top250 = ia.get_top250_movies()

# Iterate through the first 20 movies in the top 250
for movie_count in range(0, 20):
    # First, retrieve the movie object using its ID
    movie = ia.get_movie(top250[movie_count].movieID)
    # Print movie title and genres
    print(movie['title'])
    print(*movie['genres'], sep=", ")
