Check If Pid Exists On Windows With Python Without Requiring Libraries

Is there a way to check if a PID exists on Windows with Python without requiring libraries? How to?

Solution 1:

This is solved with a little cup of WINAPI.

defpid_running(pid):
    import ctypes
    kernel32 = ctypes.windll.kernel32
    SYNCHRONIZE = 0x100000

    process = kernel32.OpenProcess(SYNCHRONIZE, 0, pid)
    if process != 0:
        kernel32.CloseHandle(process)
        returnTrueelse:
        returnFalse

Solution 2:

This works on my system..

>>>import subprocess>>>out = subprocess.check_output(["tasklist","/fi","PID eq 1234"]).strip()>>>if out == "INFO: No tasks are running which match the specified criteria.":...print"No such PID :D"...
No such PID :D
