Python 中的 numpy.npv()
哎哎哎:# t0]https://www . geeksforgeeks . org/num py-NPV-python/
NPV(比率，价值):该财务函数帮助用户计算现金流系列的 NPV(净现值)。
参数:
rate : [scalar] Rate of discount
value : [array_like, shape(M,)] value of
cash flows time series. The (fixed) time interval
between cash flow “events” must be the same as that
for given rate is given. By convention, investments
or “deposits” are -ve, income or “withdrawals” are +ve
返回:
present value as per given parameters.
正在求解的方程:
代码 1:工作
## Python program explaining pv() function
import numpy as np
# rate values
a = np.npv(0.281,[-100, 19, 49, 58, 200])
print("Net Present Value(npv) : ", a)
输出:
Net Present Value(npv) : 46.5579792365
