C-M would be '\x0d'. you can look at the ascii(7) manual page
for the codes, or type something like print hex(ord('^M')) at
the prompt. the way to insert a literal ^M there is to first
type ^V to prevent readline or the tty driver from meddling with it.

string.translate()/string.maketrans() probably.
