When building a Python script to generate a legal report, begin by clearly organizing your hardcoded input data. For this scenario, you will need two lists: one containing dictionaries for case summaries (with fields like `"case_id"`, `"title"`, `"status"`, and `"summary"`), and another for compliance events (with fields such as `"event_id"`, `"description"`, `"deadline"`, and `"status"`). 

To create the report, filter the case summaries to include only those where the status is `"open"`. For compliance events, select those with deadlines in the future and a status that is not `"completed"`. Format your report as a readable string, grouping open cases and upcoming compliance deadlines under clear headings. Use string concatenation and formatting to ensure your report is well-structured, with each case and event presented on its own line and details clearly labeled. Finally, assign the complete report string to a variable, such as `legal_report`, so it can be used or printed as needed.
