Cover image for I built a Python automation
I built a Python automation tool for logistics that processes shipment Excel files and tracks delivery status automatically. The tool reads tracking numbers from different carriers (DHL eCommerce, DHL Spain, DHL Freight), checks shipment status through APIs or Selenium when APIs are not available, downloads POD documents, and stores them locally. After that, the system uploads POD files to Google Drive and generates a report showing which shipments are delivered, pending, or already uploaded.
