This is a extremely simple line of code:

 
The from ctypes import * 
Kernel32=windll. Kernel32 
A=eval (input (' PID)) 
Kernel32. DebugActiveProcess (a) 
Print (' error='kernel32. GetLastError ()) 

At least I don't see what problem, but, no matter what input PID, an error results are "6"...
More than that, I tried a lot of the kernel function are derived error '6',
Excuse me what's going on?
