Word count
A metric that counts word units in text, either overall or for a specified word, according to the applicable segmentation rule.
The Quick Python Book, Fourth Edition
A word count is the number of words identified in a text according to a specified word-segmentation rule.
- How it is used
- Measures words in a file alongside line and character counts, or counts occurrences of individual words.
- How deep it goes
- Works through split-based counting, line-by-line accumulation, alphabetic filtering, and dictionary frequencies without defining a universal word boundary.
- Examples
- Uses a four-line sample reporting 30 words and a cleaned text file ranked by most and least common words.
- What you can do after
- Build it from scratch as a Python file counter, then adapt it for alphabetic-only counts or per-word frequencies.

The number of whitespace-delimited words represented by a character sequence or word-count summary.
- How it is used
- Motivates monoidal parallel parsing by showing why split substrings require richer results than integer counts.
- How deep it goes
- Derives a `WC` algebraic data type, all four combine cases, law tests, and a character-folding implementation.
- Examples
- Works through splitting "lorem ipsum dolor sit amet, " inside "dolor" and combines the resulting `Part` values.
- What you can do after
- Build it from scratch by defining a lawful `WC` monoid and folding whitespace-classified characters into a final count.
