Best Practices - Data Blocks

Structure the development of the data block as a unit test. Create 3 functions to simulate the data block layer.
Function 1: Returns the data set(s) required for the business report.
Function 2: This will contain the business logic required for the report creation including the data import from function 1.
Function 3: This executes function 2 by providing the required parameters.

Use a calculation environment that contains only the required packages.

Usage of packages such as pandas should be reserved for instances where significant data preparation is required. If not, use dictionaries to process the data

Make sure there are no unused variables in the script.

Do not hard code any variables within function 2 referenced above.
