{'characters': 52, 'words': 10, 'lines': 2, 'most_common_words': [('the', 3), ('dog', 2), ('quick', 1)]}

How it works

The Counter from the collections module tallies word frequencies efficiently. text.split() splits on whitespace and counts words; text.count("\n") + 1 gives line count, assuming text ends without a newline. The function returns a dictionary with easy-to-read metrics. This pattern is useful for quick text analysis without external dependencies.

Common mistakes

Forgetting to lower-case text before counting most common words, causing case-sensitive duplicates.
Counting a trailing newline as an extra line when using `count("\n") + 1` without adjusting for empty lines.
Assuming `split()` splits on punctuation, but it only splits on whitespace.

Variations

Use `re.findall(r'\b\w+\b', text.lower())` to count words with regex for better punctuation handling.
Return a sorted list of all word frequencies instead of only the top 3.

Real-world use cases

Generating content statistics for a blog post editor to show word count and readability hints.
Analyzing log files to identify the most frequent error messages for troubleshooting.
Building a simple text summary tool that reports key metrics before further NLP processing.
