h.  Input five subject's marks in a list and print the percentage of all.

                             i.  Create a list with heterogeneous values and print the values which are only integer.
                             j.  Create a list of five subject's marks and print the marks >50.
                          4.  Find the output of the following programs:
                                a.  A list is declared as

                                    marks = [20,15,45,25,30]
                                    What will be the output of
                                    print(3*marks[2] - 4*marks[4])
                                b.  word=['P','R','O','G','R','A','M']
                                    print(word[-4:])
                                    print(word[::-2])
                                c.  word=['P','R','O','G','R','A','M']
                                    print(word.count('R'))
                                    print(word.index('R'))
                                d.  L=[1,2,3]
                                    L*=3
                                    print(L)
                                e.  list1=[10,20]
                                    list2=[30,40]
                                    list1.append(25)
                                    print(list1)
                                    list1.extend(list2)
                                    print(list1)
