Binary string sounds ambiguous. Firstly, everything is binary. Secondly,
strings are byte strings or Unicode strings. In any case, I'm not 100% sure
what you mean - giving an example of input and output would help!

If you need a piece of four bytes which contain a number in a packed format
similar to the one used in memory, using bin(x) is the wrong way. Instead,
take a look at the struct module:
Alternatively, also the array module might help.
