  • 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
    # Importing pandas and matplotlib
    import pandas as pd
    import matplotlib.pyplot as plt
    # Start coding!
    netflix_df = pd.read_csv("netflix_data.csv")
    # Filter the data to remove TV shows and store as netflix_subset.
    netflix_subset = netflix_df[netflix_df["type"] == "Movie"]
    # Investigate the Netflix movie data, keeping only the columns "title", "country", "genre", "release_year", "duration", and saving this into a new DataFrame called netflix_movies.
    netflix_movies = netflix_subset[["title","country","genre","release_year","duration"]]
    # Filter netflix_movies to find the movies that are shorter than 60 minutes, saving the resulting DataFrame as short_movies; inspect the result to find possible contributing factors.
    import numpy as np
    short_movies = netflix_movies[netflix_movies["duration"] < 60]
    # Using a for loop and if/elif statements, iterate through the rows of netflix_movies and assign colors of your choice to four genre groups ("Children", "Documentaries", "Stand-Up", and "Other" for everything else). Save the results in a colors list. 
    colors = []
    for label, row in netflix_movies.iterrows() :
        if row["genre"] == "Children" :
        elif row["genre"] == "Documentaries" :
        elif row["genre"] == "Stand-Up":
    import matplotlib.pyplot as plt
    # Initialize a figure object called fig and create a scatter plot for movie duration by release year using the colors list to color the points and using the labels "Release year" for the x-axis, "Duration (min)" for the y-axis, and the title "Movie Duration by Year of Release".
    fig = plt.figure() 
    plt.scatter(netflix_movies.release_year, netflix_movies.duration, c=colors)
    plt.ylabel("Duration (min)")
    plt.xlabel("Release year")
    plt.title("Movie Duration by Year of Release")
    # After inspecting the plot, answer the question "Are we certain that movies are getting shorter?" by assigning either "yes", "no", or "maybe" to the variable answer.
    answer = "maybe"
