0 pts) 1 have a dictionary defined by pointe -A 2 B:3,C: 8,"D: 3, "E:) which assigns a "point value" to some of the letters. Write code which tals a list named lets, and then prints out the sums of the point values for the elements of lets. Any letter not in the dictionary should get O peints. For ecampie,t then your code should print out 12, since 5+2+3+2+0-12 11. (5 pts) A sequence of numbers is given by 3, 10,30, 300,9000, 2700000,. where the first two elements are 3 and 10, and every element after is the product of the previous two. Write a Python function ff whose input is a positive integer n, and whose output is the nth number in the sequence. For excample ff (2) should have the value 10, and fs (4) should have the value 300
