mount command pid

Question

Trying to mount a device and get the pid of mount command.

cmd="/bin/mount /dev/sda1 /mnt"

Now how to obtain the pid of mount command? There plenty of mounted device available on my system, something like ps | grep mount won't work.

As the comments suggest I'm not sure how useful it is to get the mount pid, but if you use the subprocess module you can easily get the pid.

>>> import subprocess
>>> p = subprocess.Popen("ls", shell=True)
>>> p.pid
4136
