Fix Spelling Mistakes in Python Like a Pro!

Introduction – Fix Spelling Mistakes in Python

In this article, we’ll learn how to auto-correct miss-spelled words using pyspellchecker library. Discover how this library can help you effortlessly identify and rectify misspelled words, boosting the quality of your text and elevating your online credibility.

Understanding the Spell Checking Landscape

The art of spell checking involves identifying words that are absent from a predetermined dictionary. Traditional spell checkers rely on static lexicons to verify word correctness. However, the pyspellchecker library takes a more dynamic approach by harnessing the power of the Levenshtein Distance algorithm, also known as the Edit Distance algorithm, which measures the similarity between two strings by calculating the minimum number of single-character edits required to transform one string into the other. In simpler terms, it’s like finding the shortest path to transform “kitten” into “sitting” – changing just a few letters at a time.

Fix Spelling Mistakes in Python code implementation

Let’s dive into an example to illustrate the effectiveness of the pyspellchecker library. Imagine you have a text riddled with potential misspelled words:

pip install pyspellchecker

from spellchecker import SpellChecker


def correct_spelling(text):
    # Create a SpellChecker instance
    spell = SpellChecker()

    # Split the input text into words
    words = text.split()

    corrected_words = []
    for word in words:
        # Check if the word is misspelled
        if spell.unknown([word]):
            # Get the corrected version of the word
            corrected_word = spell.correction(word)
            corrected_words.append(corrected_word)
        else:
            corrected_words.append(word)

    # Join the corrected words back into a sentence
    corrected_text = " ".join(corrected_words)
    return corrected_text


# Input text with potentially misspelled words
input_text = "Ths is a proofessional text with some misspeled wrds."

# Correct the spelling in the input text
corrected_text = correct_spelling(input_text)

print("Original text:", input_text)
print("Corrected text:", corrected_text)

Output

Original text: Ths is a proofessional text with some misspeled wrds.
Corrected text: the is a professional text with some misspelled words

It also supports other languages like English – ‘en’, Spanish – ‘es’, French – ‘fr’,Portuguese – ‘pt’, German – ‘de’, Russian – ‘ru’, Arabic – ‘ar’, Basque – ‘eu’, Latvian – ‘lv’

To set a language: Let’s try to correct spelling in Python for Spanish text

spell = SpellChecker(language='es') // use the short language code

from spellchecker import SpellChecker

# Create a SpellChecker instance
spell = SpellChecker(language='es')  # 'es' for Spanish

# Input text in Spanish with potential misspellings
input_text = "Este es un ejemple de texto con algunas palbras mal escrtas."

# Split the input text into words
words = input_text.split()

corrected_words = []
for word in words:
    # Check if the word is misspelled
    if spell.unknown([word]):
        # Get the corrected version of the word
        corrected_word = spell.correction(word)
        corrected_words.append(corrected_word)
    else:
        corrected_words.append(word)

# Join the corrected words back into a sentence
corrected_text = ' '.join(corrected_words)

print("Original text:", input_text)
print("Corrected text:", corrected_text)

Original text: Este es un ejemple de texto con algunas palbras mal escrtas.
Corrected text: Este es un ejemplo de texto con algunas palabras mal escritas
