[Tutor] how to struct.pack a unicode string?

Hi, How can I pack a unicode string using the struct module? If I simply use packed = struct.pack(fmt, hello) in the code below (and 'hello' is a unicode string), I get this: error: argument for 's' must be a string. I keep reading that I have to encode it to a utf-8 bytestring, but this does

A clarification: in the default mode ('@'), struct uses native alignment padding, but not if you override this with , , =, or !, as you did. fmt = endianness + str(len(hello)) + s That's the wrong length. Use the length of the encoded string. Generally, however, you'd use a fixed size set by
