python loop with list and array-CodePudding

I need to loop through ( list and array) as below

f=[2,3]
b=np.array([1,2],[2,3])


total=(f[0]*(b[0][0] b[0][1]) (f[1]*(b[1][0] b[1][1])

I want to do this using loop with sum, because the actual equation is more complicated.

so total=sum(F*(b b))

How can this be done?

CodePudding user response：

If you need to generalise dimensions of an array, you can use the ':' index. For example,

total = 0
for i in range(2):
    total  = f[i]*sum(b[i,:])

I'll leave this here as well: Understanding slice notation
