   40. It's a prefix to indicate the number is in hexadecimal rather than in some other base. The programming language uses it to tell compiler.

   The second line formats it as a hexadecimal string, padded to (len(bstr) + 3) // 4 hex digits, which is number of bits / 4 rounded up, i.e. the number of hex digits required. The last part of the second line parses the binary string to a number, because the %X format specifier is for numbers not binary strings. –
