Answer 1

Can you show a snippet of your python code? Will make it easier to see where things are going wrong. If not here are a few checks you can do to see if everything should work.

1: Does the table show any errors before the step where you use the Python scripts? If so python may throw some errors, as power bi dumps the table to a dataframe, if there are errors in it the dataframe won't now how to represent them.

2: It may be a good idea to test your python code in a seperate editor first ( So make a dummy Dataframe in place of your table with maybe a few rows, and make sure your scripts executes just fine ( may be good to use the most extreme values occuring in your table for your test case )

3: Make sure to store your desired result in a pandas dataframe. Power BI takes all Dataframe objects in your script after executing, and allows you to dump them into a power query table.
