Ecommerce Purchases Exercise - Solutions




Ecommerce Purchases Exercise - Solutions

In this Exercise you will be given some Fake Data about some purchases done through Amazon! Just go ahead and follow the directions and try your best to answer the questions and complete the tasks. Feel free to reference the solutions. Most of the tasks can be solved in different ways. For the most part, the questions get progressively harder.

Please excuse anything that doesn't make "Real-World" sense in the dataframe, all the data is fake and made-up.

Also note that all of these questions can be answered with one line of code.


Import pandas and read in the Ecommerce Purchases csv file and set it to a DataFrame called ecom.


In [84]:
import pandas as pd

In [86]:
ecom = pd.read_csv('Ecommerce Purchases')

Check the head of the DataFrame.


In [87]:
ecom.head()
