Purcase analytics

Purchase analytics is a script that takes order and product information from the Instacart 2017 database and outputs a csv file with the number of orders per department, how many orders are new (not a re-order), and percentage of new orders from total orders.

Instracart 2017 data available here:
https://www.instacart.com/datasets/grocery-shopping-2017

Usage

Navigate to root directory (./insight_shnitkind/) and run run.sh or excecute the following:

python ./src/purchase_analytics.py ./input/order_products.csv ./input/products.csv ./output/report.csv
