I have some strings like : `'I go to by everyday'` and `'I go to school by bus everyday'` and `'you go to home by bus everyday'` in python. I want to know that is it possible to convert the first one to the other ones **only by inserting** some characters ? if yes get the characters and where they must to insert! I used `difflib.SequenceMatcher` but in some string that have duplicated words it didn't work!
