Hello,
Python 2.7.10, Windows 7
"ValueError: invalid \x escape"
Note that there is no indication of where is the error (no line number).
the faulty ligne is a # commented line inside a """ commented block.
"""
. . .
#s.send("PRIVMSG bot :!voice %s\x\n" % n)

changing "\x" to "\x12" (for example) fixes the error.
