Pykd support for Python 3.4
Atm the only way to run pykd on Windows XP and Server 2003 is to use Python 2.7.
This is because there is no way to install Python 3.5 and above on XP/2003. And Pykd only support 3.5 and above in Python 3.
However, sometimes you want to debug something in userland on a Windows XP or 2003 VM so you install WinDbg. However you can't use Python 3. So all the scripts you develop for other Windows versions for pykd/Python 3 don't work. You are force to revert to Python 2.7.
