Web2 days ago · Return the hexadecimal representation of the binary data. Every byte of data is converted into the corresponding 2-digit hex representation. The returned bytes object is therefore twice as long as the length of data. Similar functionality (but returning a text string) is also conveniently accessible using the bytes.hex () method.
