Binary to Decimal converter works backwards

I have created a basic program for converting 8-bit binary to decimal, but when I run the program, it works backwards, e.g. if I enter the binary number '00000001' the program will return 128. Here is my code:

binaryvalue=input("Please enter your 8 bit binary number.")

binaryvalue=str(binaryvalue)

if len(binaryvalue) <= 8:

    print("Your number is accurate.")
    value_index=0
    total=0
    print("Your number is valid.")
    for i in range(len(binaryvalue)):
        total = total + (int(binaryvalue[value_index])) * 1 * (2**(value_index))
        value_index = value_index+1
    print("Your decimal number is: "+str(total))

So, as mentioned by jonrsharpe and Moe

reverse the input:

binaryvalue = str(binaryvalue)[::-1]

or, you can place the offset in your power:

total = total + (int(binaryvalue[value_index])) * 1 * (2**(len(binaryvalue)-value_index-1))

Both are essentially doing the same thing though.
