Short, object-oriented programming is to wrap a class class outside of a function program, and then point the class to an objectAnd the functions in class are called methods here.As an example:Use functional programming to write a script that sends a message in one click:def e_mail (email,message): print (' mail sent ... ') return truee_mail (' [email protected] ', ' email content ')　　Use object-orien

('Please input the minutes :...'))Hours = minutes/60Mins = minutes-hours * 60Print "% I: % I" % (hours, mins) 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
