Project: Investigating Netflix Movies


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:

The data


show_idThe ID of the show
typeType of show
titleTitle of the show
directorDirector of the show
castCast of the show
countryCountry of origin
date_addedDate added to Netflix
release_yearYear of Netflix release
durationDuration of the show in minutes
descriptionDescription of the show
genreShow genre

# Plotting movies by year
plt.scatter(netflix_movies.release_year, netflix_movies.duration, c=colors)

# Renaming the x and y axis
plt.title('Movie Duration by Year of Release')
plt.xlabel('Release year')
plt.ylabel('Duration (min)')
# Answering the project question of "Are we certain that movies are getting shorter?"
answer = 'maybe'
