How to write ETL operations in Python

Clean and transform raw data into an ingestible format using Python. In this article, you’ll learn how to work with Excel/CSV files in a Python environment to clean and transform raw data into a more ingestible format. This is typically useful for data integration.

In this article, you’ll learn how to work with Excel/CSV files in a Python environment to clean and transform raw data into a more ingestible format. This is typically useful for data integration.

This example will touch on many common ETL operations such as filter,** reduce, explode,and **flatten.

Notes

The code for these examples is available publicly on GitHub here, along with descriptions that mirror the information I’ll walk you through.

These samples rely on two open source Python packages:

• pandas: a widely used open source data analysis and manipulation tool. More info on their  site and  PyPi.
• gluestick: a small open source Python package containing util functions for ETL maintained by the  hotglue team. More info on  PyPi and  GitHub.

Without further ado, let’s dive in!

Introduction

This example leverages sample Quickbooks data from the Quickbooks Sandbox environment, and was initially created in a  hotglue environment — a light-weight data integration tool for startups.

Data Quality Testing Skills Needed For Data Integration Projects. Data integration projects fail for many reasons. Risks can be mitigated when well-trained testers deliver support. Here are some recommended testing skills.

In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.
