How to subtract a value from one of value in a numpy array

I have an array from which I need to subtract the a value from one of the value in the array

I followed the suggestion given in this link. But didn't work in my case

My sample code is given below. In this , I wanted to subtract '1' from the second value of array (as mentioned in the function sig2(k).

I have tried as per the below link. But couldn't succeed.

Can some one let me know where am I going wrong

Subtract from first value in numpy array 

import numpy as np

k = [1,3]
coe = np.array([[k[0],k[1]]])

def sig2(k):
    return k[0] * np.power(lam1,((k[1]=-1)))

print(sig2(k))

Check the below code, is this what you want? 

import numpy as np

k = [1,3]
coe = np.array([[k[0],k[1]]])
lam1 = 5
def sig2(k):
    k[1] -= 1
    return k[0] * np.power(lam1,(k[1]))

print(sig2(k))

Output

25
