What This Artifact Does

A Python utility that provides Counter-based functionality extracted from real Python documentation:

1. count_words(text) - Counts word occurrences in text using Counter
2. count_items(items) - Counts hashable items in a list using Counter
3. most_common(counter, n) - Returns n most frequent items
4. counter_to_dict(counter) - Converts Counter to regular dict
5. extract_counter_description(doc_content) - Parses documentation to extract Counter info

Verification Results

• 4/4 tests passed
• Word counting: Verified 'the' appears 3 times, 'fox' appears 2 times
• Missing key handling: Counter returns 0 for missing keys (not KeyError)
• Counter operations: Addition, intersection, union all verified
• Documentation extraction: Parses web-extracted content correctly
