With 0x{:02x} the 0x is simply removed, whereas with the {:#04} formatter one would need to remove both the # and substitute the 04 for 02. It formats three numbers as 2 digit hexadecimal strings with leading 0s used if the number only consists of a single digit in hex. The '#' is just a literal character.
