Answer 1

(1 + 0.014) ** L is equal to 1.014^L where L is a list

Answer 2

Then you can easily do it using map function,

L = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]

U = list(map(lambda x:(110000 - 45000) / ((1 + 0.014) ** x),L))

print(f"NPV: {sum(U)}")

I can't figure how to do using starmap or accumulate.

Answer 3

Mary_d9 what do you want to do ? Can you show the output you are expecting ?

Answer 4

And how does that output comes?

Answer 5

Abhay I have a formula: (rd - rz) / (1 + r) ** n and n are elements of a list, I need to execute this formula with different n and add all the values together like (rd - rz) / (1 + r ) ** 1+ (rd - rz) / (1 + r) ** 2 and so on

Answer 6

Mary_d9 you have to use starmap or accumulate only?

Answer 7

Abhay thank you😊

Answer 8

Abhay how can my function be used for each item of "L" using accumulate or starmap? or is it impossible?

Answer 9

Abhay output: 13604.501252379501

Answer 10

Abhay not necessary
