When you open a file in binary mode, then you are essentially working with the bytes type. So when you write to the file, you need to pass a bytes object, and when you read from it, you get a bytes object. In contrast, when opening the file in text mode, you are working with str objects.
Usually you would convert the incoming string into a Python unicode string and that can be done like this (Python 2): def decode_binary_string(s, encoding='UTF-8'): byte_string = ''.join(chr(int(s[i*8:i*8+8],2)) for i in range(len(s)//8)) return byte_string.decode(encoding)
