Converting binary to decimal integer output

Question

I need to convert a binary input into a decimal integer. I know how to go from a decimal to a binary:

n = int(raw_input(\'enter a number: \'))
print \'{0:b}\'.fo         


        

Answer 1

Try this solution:

def binary_int_to_decimal(binary):
    n = 0
    for d in binary:
        n = n * 2 + d

    return n
