Now let‘s get hands-on with the technical integration details.

Step-by-Step Process for Integration

Here is an easy 7 step checklist to connect Python with Power BI desktop on your Windows machine:

Step 1: Install Python

Download the latest Python interpreter i.e. Python 3.7 or higher from the official site using this link. While installing, remember to check the option to add Python to your system environment variables for ease of use.

Step 2: Install Critical Libraries

Open command prompt and use the pip install command to set up pandas, matplotlib, numpy and other essential Python data libraries on your machine as shown:

pip install pandas==1.4.2
pip install matplotlib==3.5.1 
pip install numpy==1.22.3

This equips your system for data analytics and visualization using Python.

Step 3: Install Power BI Desktop

Download the Power BI desktop from Microsoft using this link for free. I recommend installing the latest monthly release for access to the newest features.

Step 4: Configure Python Integration

Launch Power BI desktop on your system. Within the top menu, navigate to File > Options and Settings > Python Scripting. Enter the file path location of your preferred Python interpreter installation in the dialog box as highlighted below:

Configuring Python in Power BI

Ensure you are able to establish a valid connection too. This allows seamless usage of the Python engine from within Power BI.

Step 5: Import Data using Python Scripts

Click on Get Data from the top menu and select the Python script option as shown:

Import Python Script Power BI

Here you can input a Python script that fetches source data from APIs or databases and returns a Pandas dataframe object containing rows and columns just like a table. This output dataframe will automatically get imported into the Power BI data model.

For example:

import pandas as pd
import requests

table_data = pd.DataFrame(requests.get(‘https://api.data.gov/ed/collegescorecard/v1/schools?‘).json()) 

return table_data

This script uses the Requests library to extract US education data via API into a Pandas dataframe. As you can see, Python allows gathering data from virtually any digital source.

Step 6: Enable Custom Visualizations

Within the Visualizations pane, click on the ellipsis (…) to open the extended visualizations gallery. Here you can enable the Python visual icon to start building visuals via Python code.

You can utilize visualization libraries like Matplotlib, Plotly etc. to now create charts, graphs and maps using your dataset.

For example, to plot a simple bar chart in Python:

import matplotlib.pyplot as plt

plt.bar(table_data[‘SCHOOL.NAME‘], table_data[‘GRAD.DEBT.MDN‘])

Dragging and dropping data fields automatically creates supporting boilerplate code making things easier. Custom Python visuals now appear alongside standard Power BI visuals within your reports.

Step 7: Schedule Refresh to Trigger Python Scripts

You can configure Power BI refresh to trigger key Python scripts automatically based on schedules. This helps automate steps to process latest data, recreate predictive models, update report parameters and more.

Here is one template to try:

import pandas as pd
from datetime import datetime

now = datetime.now() 

log = {‘TimeRan‘: now}

print(f‘Script run at {now} via Power BI‘) 

# Insert Python logic here to extract and process data

return pd.DataFrame([log]) 

With these 7 steps complete, you‘ve unlocked the full potential of Power BI using Python!

Next, let‘s explore some real-world examples of this integration in action.
