Python: Get process and parent process ids

‘os’ module provides getpid(), getppid() methods to get process id and parent process ids.

Method	Description
os.getpid()	Return current process id
os.getppid()	Return parent process id. On UNIX systems, if the parent process exits before child process, then the id returned is the one of the init process (1), on Windows it is still the same id, which may be already reused by another process.

import os

def getProcessId():
    print("Process Id : ",os.getpid())
    print("Parent process Id : ",os.getppid())

if(__name__=="__main__"):
    getProcessId()

Output

Process Id :  70024

Parent process Id :  57995
