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

ColumnDescription
show_idThe ID of the show
typeType of show
titleTitle of the show
directorDirector of the show

release_yearYear of Netflix release
durationDuration of the show in minutes

# Importing pandas and matplotlib
import pandas as pd
import matplotlib.pyplot as plt

# Start coding!
#Loading and inspecting CSV file
netflix_df = pd.read_csv("netflix_data.csv")
#viewing the first 5 rows
netflix_df.head(5)
netflix_subset = netflix_df[netflix_df["type"] == "Movie"]
netflix_subset
#subsetting the netflix subset and only keeping columns title,genre,country,release year and Duration
netflix_movies = netflix_subset[["title","country","genre","release_year","duration"]]
netflix_movies
#only keeping movies that have a duration of less than 60 in short_movies
short_movies = netflix_movies[netflix_movies["duration"] < 60 ]
#displaying the first 20 rows
short_movies.head(20)
#adding colors based on genres 
colors = []
for lab, row in netflix_movies.iterrows():
    #for children RED color
    if row['genre'] == "Children":
        colors.append("red")
    #for Documentries BLUE color
    elif row['genre'] == "Documentaries":
        colors.append("blue")
    #for StandUp GREEN color
    elif row['genre'] == "Stand-Up":
        colors.append("green")
    #for everything else PURPLE color
    else:
        colors.append("purple")
#printing and checking the list outside FOR LOOP      
print(colors)
#Creating a scatter plot labelling it and adding color based on the color list we created before
import matplotlib.pyplot as plt
fig = plt.figure(figsize=(12,8))
plt.scatter (netflix_movies['release_year'],netflix_movies['duration'], c=colors)
plt.xlabel("Release year")
plt.ylabel("Duration (min)")
plt.title("Movie Duration by Year of Release")
plt.show()
Are we certain that the movies are getting shorter?
answer = "maybe"
