Import multiple dataframes from Python script

Hi Anonymous ,

A limitation of visuals (core, custom, R, Python or otherwise) is that they can only execute a single DAX query , and therefore only contain a single dataset, so it is not possible to use two independent data frames. The only way around this might be to to combine all the data as a single dataset and then process into independent data frames accordingly before you start doing your main body of work.

The boilerplate code is a series of comments informing you what pre-processing Power BI does to the dataset prior to the point where you add your code, as well as how to access the visual data (i.e. though the named dataset variable). If this were missing and you had not read the relevant documentation then it might not be clear how to proceed withough seeking information elsewhere. It's basically a succinct version of this section of the doc:

As you select or remove fields, supporting code in the Python script editor is automatically generated or removed.

Based on your selections, the Python script editor generates the following binding code.

• The editor created a dataset dataframe, with the fields you added.
• The default aggregation is: do not summarize.
• Similar to table visuals, fields are grouped and duplicate rows appear only once.
