Scheduling and Batch Processing with Python
Batch processing is a powerful tool for government analysts who need to automate repetitive tasks across large datasets. In many government workflows, you often face the challenge of processing similar data from multiple sources, such as service usage records from different regions or time periods. Instead of analyzing each dataset manually, batch processing allows you to automate these tasks using loops and functions, saving time and reducing the risk of human error. This approach is especially useful when you need to apply the same analysis or transformation to multiple datasets, ensuring consistency and efficiency across your work.
1234567891011121314# Process service usage data for multiple regions using a loop regions = ["North", "South", "East", "West"] usage_data = { "North": [120, 130, 125], "South": [110, 115, 117], "East": [140, 145, 142], "West": [100, 105, 102] } for region in regions: data = usage_data[region] avg_usage = sum(data) / len(data) print(f"Average usage in {region}: {avg_usage}")
To structure your code for batch processing, you should organize your workflow into clear, repeatable steps. Define functions that handle individual tasks, such as processing a single dataset or calculating summary statistics. Use loops to iterate over each dataset, calling your function for each item. Error handling is critical in batch processing; if an error occurs with one dataset, you want your script to log the error and continue processing the remaining items, rather than stopping entirely. This way, you can review any issues afterward and ensure that the majority of your data is still processed successfully.

1. What is batch processing, and why is it useful?
2. How can you handle errors during batch processing in Python?
3. What is the benefit of collecting results into a summary structure?
