参数：
values : [array-like] Input cash flows per time period. net “deposits” are negative and net “withdrawals” are positive
finance_rate : Interest paid on cash amounts.

# Python program explaining  
# mirr() function  
  
import numpy as np  
'''  
Question:  
  
    Investmnt = 500 
    Withdrawls at regular interval:50, 31, 3, 11 
'''
  
Solution = np.mirr([-500, 50, 31, 3, 11], .34, .21) 
  
print("Solution - Modified Internal Rate of Return:", Solution) 

输出：

Solution - Modified Internal Rate of Return: -0.26165615714437973
