Of course! And, why not escape everything else, too?
abc -> ^a^b^c
echo %PATH% -> ^e^c^h^o^ ^%^P^A^T^H^%
In all seriousness, to me this is obvious. When you pass a command to the
shell, naturally, certain details are shell-specific.
-10000. Bad idea. Very bad idea. If you want the ^ to be escaped, do it
yourself. Or better yet, don't pass shell=True.
