Leveraging Python for Data Integration in Power BI

Chapter 1: Introduction to Python in Power BI
Welcome!
In this guide, we will explore how to integrate Python as a data source within Power BI. For those unfamiliar, Power BI is a Microsoft business analytics tool that allows users to create interactive visualizations and offers self-service business intelligence features. I personally find this platform to be user-friendly and remarkably efficient. If your reporting needs are straightforward, you can construct an entire report without writing any code.
In this tutorial, we will focus on importing data using Python. If you're interested in learning more about data visualizations, feel free to check out my other tutorials.
Section 1.1: Prerequisites and Audience
For this tutorial, you will need the following:
- Python 3.x (including pandas and numpy)
- Power BI
This content is tailored for:
- Intermediate Python users (familiar with pandas)
- Intermediate Power BI users
Section 1.2: Establishing a New Data Source
To get started, open Power BI and navigate to Get Data -> Python:
Next, use the following code for this tutorial, though feel free to utilize any pandas dataframe:
If successful, you should see a window similar to this:
If you encounter an error, it may stem from one of the following issues:
- Errors in your code. I recommend testing your code in your preferred IDE first. Once verified, copy and paste it back into the Power BI editor.
If the output matches the image above, select the appropriate table that corresponds with your dataframe name and click on transform data. You will then access the Power Query window. Ensure that all data is imported as intended. If no transformations are needed, congratulations—you've just set up your first Python Data Source!
If modifications are necessary, you have two options:
- Make changes in Power Query. I recommend this approach as it is generally quicker than doing it in Python, allowing you to perform most transformations directly within Power BI.
To modify your data using Python, navigate to Transform -> Run Python script and make your changes there:
After completing your modifications, click on Close & Apply, and your data will load into the model.
