Spell checker using Python

Spell checker:

This program uses a simple approach to spell correction, it uses a dictionary of words and their frequency of occurrence in a big corpus of text, and it uses the probability of a word in the dictionary to decide which word is the most likely correction for a misspelled word. The program defines four functions: candidates(), known(), edits1(), and edits2(), which are used to generate possible spelling corrections for a given word.

Please note that this is just an example, and you may need to adjust the code depending on your specific requirements, and you may also need a large corpus of text to train your model.
