So now you have put textcorrect inside the class Ex3. But that means
that it is an instance method now. So you need to call
otherwise it is not known. But then you must also give it a self
parameter. The same applies to the other methods, so in textcorrect you
have to call self.correct(i) and give correct a self parameter. etc.
Or you make them all static methods and use Ex3.textcorrect().
I don't think putting all the methods in a class is a good idea, as you
only need one instance of it and most methods are static-like anyway.
Putting it in a class is a Java-ism. A module for this is more Pythonic.
