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

This is the full thing

binary = input('enter a number: ')
decimal = 0
for digit in binary:
decimal= decimal*2 + int(digit)

print (decimal)
