Is there a module that sets the parity of a string? I have an

So what I need is before sending the message, convert it from space to
even parity. And when I get the response I need to convert that from
even to space parity.
By what means are the messages being delivered? I've rarely
seen parity used outside of simple RS-232-style serial communications.
Certainly not (in my experience, though it's doubtless been done)
in TCP/IP based stuff. And if it's serial, parity can be
supplied at a lower level than your code.
As to the specific question: a module is not really required.
The parity value of a character depends only on the binary
value of that one byte, so a simple 128-byte substitution
table is all you need, plus a call to string.translate for
each string.
