I have the following python code, which converts a binary string into plain-text:
import bin ascii
n = int('01100001011000100110001101100100', 2)
binascii.unhexlify('%x' % n)
This code functions properly, but I don't understand what's going on here.
What is the purpose of the
2
at the end of the int declaration?
According to the documentation , int
can take a second argument: the base of the first argument.
What is the purpose of the
'%x' % n
argument?
%x
in a string indicates that an item will be formatted to hexadecimal with lowercase letters. '%x' % n
. It is similar to the builtin hex
function, except it doesn't have the leading 0x
in the string. An equivalent expression would be format(n, 'x')
.
