## 12.2.9 Spell Checking and Correction¶

- For natural language processing tasks, it’s important that the text be free of spelling errors
- A `Word`’s `spellcheck` method returns a list of tuples containing possible correct spellings and confidence values
- Assume we meant to type “they” but misspelled it as “theyr”

In [1]:

    from textblob import Word

In [2]:

    word = Word('theyr')

In [3]:

    word.spellcheck()

Out[3]:

    [('they', 0.5713042216741622), ('their', 0.42869577832583783)]

In [4]:

    word.correct()  # chooses word with the highest confidence value

Out[4]:

    'they'

- Word with the highest confidence value might not be the correct word for the given context
- `TextBlob`s, `Sentence`s and `Word`s all have a `correct` method that you can call to correct spelling
- Calling `correct` on a `Word` returns the correctly spelled word that has the highest confidence value

In [5]:

    from textblob import TextBlob

In [6]:

    sentence = TextBlob('Ths sentense has missplled wrds.')

In [7]:

    sentence.correct()

Out[7]:

    TextBlob("The sentence has misspelled words.")
