Power BI Desktop and Python; like Peanut Butter and Chocolate
February 13, 2019Power BI Desktop helps to visualize complex data with the help of inbuilt and custom visualizations. It allows integrating data from the various data sources and preparing visualization from it.
Microsoft recently integrated the Python programming language in the Power BI. Python is a powerful object-oriented language and is used by the data analyst and scientist to analyze complex datasets. We can now use the Python as a preview feature in the Power BI August 2018 release onwards. We can now use Python scripts to generate custom visualization.

Suppose we have created the FILESTREAM database in our instance and now we want to insert a large number of files into a FILESTREAM container. It is easy to write out the insert queries for a small number of files, but if the numbers of files were in huge quantity, it would be difficult to write out the code and insert data into it. It is difficult to manage such kind of requests regularly in the environment.
