6-10.String. Write a function to return a string similar to the input string, which requires case-sensitivity inversion. For example, if "Mr. Ed" is input, "mR. eD" should be returned as the output.[Answer]The Code is as follows:Input = raw_input ('Please input a string :...')Output =''For I in input:If I = I. upper ():Output = output + I. lower ()Else:Output = output + I. upper ()Print

1. Why encapsulation?
Encapsulation is to hide the specific implementation details of data attributes and methods and only provide one interface. Encapsulation does not concern about how objects are built.
