Common Mistakes

Using wrong keys or values that do not filter completed orders.

Orders with status "completed" should be uploaded to ERP.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that extracts ERP fields from SCADA data for orders with quantity greater than 100.

SCADA systems

erp_orders = { [1]: [2] for [3], [2] in scada_data.items() if [2]["qty"] > 100 }

Drag options to blanks, or click blank then click option'
