Write a spell checking tool that will identify all misspelled word in a text file using a provided dictionary.


The program will accept either one or two command line parameters.
1. The first command line parameter is the name of the text file that will be checked.
2. The optional second command line parameter is the name of the dictionary file – a file of words with one word per line. The default dictionary file is ref.txt.
The program will write out the misspelled words, one per line, in alphabetical order.

Extend the spell checking tool so that as well as identifying all misspelled words, the program will list the line numbers in the file where the incorrect spelling occurs.

The program will write out the misspelled words (one per line, in alphabetical order), followed by a tab character, followed by the list of line numbers that word is misspelled in,in ascending order, on the same line, separated by a single space.


Extend the spell-checking tool so that the program will also print out a list of possible correct spellings for the words.

The program will write out the misspelled words (one per line, in alphabetic order), followed (on the same line) by a single space, followed by the list of line numbers in ascending order, each separated by a single space, followed by a single space, then the list of possible correct spellings, each separated by a single space.

Find the alternate spellings by considering:
a. Words in the dictionary that are the same length but:
a. Have a pair of characters interchanged
b. Differ by one character from the misspelled word
b. Words that are one character longer or one character shorter, but otherwise match the misspelled word.

Is this an assignment ? Sure looks like it!

I don't see a question anywhere.

This could be fun... :) For this problem, all you have to do is
a big "if/elif/else" statement for every possible mis-spelling.
If you want to get really fancy, you could put all the
mis-spellings in a set() and then test the incoming word against
the set for membership...For bonus points, you could use the
anydbm module as a mapping from known-bad-spellings to the
correct spelling so it can auto-correct for you...

Then you know if the word is mis-spelled. The rest is pretty
easy. ;-)
