    def func(x):

        if isinstance(x,list):

            sum1=0

            for a in x:

                if isinstance(a,int) or isinstance(a,float):

                    sum1+=a

            return sum1

        if isinstance(x,tuple):

            sum2=1

            for b in x:

                if isinstance(b,int) or isinstance(b,float):

                    sum2=sum2*b

            return sum2

                

    L=[1,2,3,4,5]

    print (func(L))

    S=(1,2,3,4,5)

    print (func(S))

    D=[1,2,3,4,'sd']

    print (func(D))
