Python Spell Checker Program

In this article, you will learn various ways to perform a spelling check using Python programming. To ensure good content readability and accessibility, spell checking is a very important task. The text analysis data or web contents are generally so huge that the manual spell check process becomes so difficult and time-consuming. Python provides some packages that help in spell checking and also correct them. Here, we have used two modules - TextBlob and pyspellchecker.

The TextBlob is a natural language processing library and is basically used for processing textual data. It has several functionalities, such as tokenization, stemming, language translation, sentiment analysis, text classification, and much more. Here is the command to install the TextBlob library using the pip tool-

pip install textblob

The successful installation of this library looks as in the below screenshot-

The correct() method of TextBlob corrects the word if any word has a spelling mistake.

# import TextBlob 
from textblob import TextBlob 
  
txt = TextBlob("Walcome to etutorialspoint. It contains lots of davelopement resourses.")
print(txt)
  
# correct sentence
correct_txt = txt.correct() 
  
print(correct_txt) 

The Python library pyspellchecker provides a feature to find the mis-spelled word and also provides possible correction suggestions. It is supported in both Python 3 and Python 2.7. We can use this for multiple languages, including English, German, French, Spanish, and Portuguese. Here is the command to install the pyspellchecker module using the pip tool-

pip install pyspellchecker

Here, the unknown() method returns those words that are not in the frequency list. The correction() method returns the most probable result for the misspelled word and candidates() method returns a set of possible candidates for the misspelled word.

# import TextBlob 
from spellchecker import SpellChecker

spell = SpellChecker() 
  
txt = spell.unknown(["It", "contains", "lots", "of", "davelopement", "resourses"])
print(txt)

correct_txt = ""  
# correct text
for x in txt:
    print(spell.correction(x))
    print(spell.candidates(x))
