Write a function. Test real cases. Improve your solution.
Given events of the form {"date": "YYYY-MM-DD", "count": integer}, return one {"date", "count"} dictionary for every date from start_date through end_date, inclusive and ascending. Add counts for repeated event dates, report zero on dates with no events, and ignore events outside the requested range. Dates are valid ISO calendar dates, start_date is not after end_date, the range is at most 366 days, and counts are nonnegative integers. Leave all input data unchanged.

Use synchronous functions and core standard-library modules. Network requests, package installs, and interactive input() are unavailable. Return lists, string-key dictionaries, strings, finite numbers, bools, or None. Student code stops after about four seconds, after Python loads. Python engine credits. Test results support self-study and don’t certify proficiency.
