Handling Correctly Spelled Words

Throughout this chapter you’ve focused on building a spell checker with the assumption that most words would need to be compared against the entire dictionary to find misspellings. In reality, most words in most documents are spelled correctly, and we could avoid doing a lot of work if we identify correctly spelled words before calculating the edit distance to potential candidate corrections.

Use what you’ve learned in this chapter to update your spell checker to skip looking for corrections for words that are already spelled correctly.

Hint: Consider using the hashable library to generate a unique identifier for each string in your dictionary.
