Is there a formatted byte string literal in Python 3.6+?

Question

I\'m looking for a formatted byte string literal. Specifically, something equivalent to

name = \"Hello\"
bytes(f\"Some format string {name}\")

Answer 1

I managed to format a literal in order to send it through a socket:

msgIndex = 0
while(IsSomeCondition()):
  msgIndex += 1
  sock.sendto(
    b"msg number %s" % bytes(str(msgIndex), encoding="utf8"),
    (receiverIP, receiverPort)
  )
# --> b'msg number 1'
# --> b'msg number 2'
# --> b'msg number 3'

I'm using Python 3.8.5.
