Executing a Python script within SQL Server

I'm far from an expert but was recently looking this, so here's a very simple T-SQL script with embedded Python if it helps anyone (Note: assumes you have Machine Learning Services with Python all set up on SQL Server).

-- Stored proc which runs embedded Machine Learning Services scripts
EXEC sp_execute_external_script

-- The SQL query to be input to the Python script
@input_data_1 = N'SELECT TOP(100) [CustomerID], [JobNumber] 
                  FROM [dbo].[Heading] ORDER BY DateDelivery DESC',

-- Variable name for the input SQL data ('InputDataSet' is the default if none)
@input_data_1_name = N'InputDataSet',

-- The language of the script
@language = N'Python',

-- Python script itself - Just imports Pandas and creates a new DataFrame with only one of the two input columns
@script = N'
import pandas as pd
OutputDataSet = pd.DataFrame(InputDataSet["CustomerID"])
'

-- Declaring SQL columns for the output (a Pandas DataFrame)
WITH RESULT SETS (
    ("CustomerID" INT NULL)
)
