Method Overview:

  • In any modern operating system, every process will have an id usually an integer that is assigned to an active process.

  • The method getpid() of the Python os module, returns the current process Id.

  • The following screenshot lists all the processes running under the operating system ( the list that can be shown to the current user)  along with the process Ids as given by the command ps -A.os.getpid() method in Python

Example 1:

import os

 

print("PID of the current process is:")

print(os.getpid())

 

Output:

PID of the current process is:

2842

 

 

Example 2:

import os

 

retVal  = os.fork()

pid     = os.getpid()

 

if retVal is 0:

    print("PID of the child process is: %d"%(pid))

else:

    pid     = os.getpid()

    print("PID of the parent process is: %d"%(pid))

 

 

Output:

PID of the parent process is: 2850

PID of the child process is: 2851
