Gregory P. Smith <greg at krypto.org> added the comment:
FYI - micropython added an optional 'sep' second argument to binascii.hexlify() that is a single character separator to insert between every two hex digits.
given the #9951 .hex() methods we have everywhere (and corresponding .fromhex), binascii.hexlify is almost a legacy API. (but micropython doesn't have those methods yet). one key difference? hexlify returns the hex value as a bytes rather than a str.
just adding a couple of parameters to the hex() method seems fine. a separator string and a number of bytes to separate.
yet another minilanguage would be overkill. and confusing in the face of the existing numeric formatting mini language ability to insert , or _ separators every four spaces ala f'{value:_x}'.
