Netflix! What started in 1997 as a DVD rental service has since exploded into one of the largest entertainment and media companies.

Given the large number of movies and series available on the platform, it is a perfect opportunity to flex your exploratory data analysis skills and dive into the entertainment industry. Our friend has also been brushing up on their Python skills and has taken a first crack at a CSV file containing Netflix data. They believe that the average duration of movies has been declining. Using your friends initial research, you'll delve into the Netflix data to see if you can determine whether movie lengths are actually getting shorter and explain some of the contributing factors, if any.

You have been supplied with the dataset netflix_data.csv , along with the following table detailing the column names and descriptions:

# Creating the dataframe by importing the "netflix_data.csv" file.

netflix_df = pd.read_csv('netflix_data.csv')

# Subsetting the dataframe for movies.

netflix_subset = netflix_df[netflix_df['type'] == 'Movie']
# Subsetting the dataframe for additional columns

netflix_movies = netflix_subset[['title', 'country', 'genre', 'release_year', 'duration']]
# Filtering for movies with a duration fewer than 60 minutes

short_movies = netflix_movies[netflix_movies['duration'] < 60]
print(short_movies[0:20])
# Assigning colors to movie genres

colors = []

# Creating a figure
fig = plt.figure(figsize=(12, 8))
# Plotting movies by year
plt.scatter(netflix_movies.release_year, netflix_movies.duration, c=colors)

# Renaming the x and y axis

plt.xlabel('Release year')
plt.ylabel('Duration (min)')

plt.show()
# Answering the project question of "Are we certain that movies are getting shorter?"
answer = 'maybe'
