Need the specific command to get a particular value from df command

I am running a python script to get few commands to get executed on a remote aix server. The command is to get the size of a file system.

command : df -g | grep -w /

output :

/dev/hd4 0.94 0.87 8% 3865 2% /

I only want 0.87 as output which is the third column of output. I want to extract the value in a variable but grep will give me a scalar value. Please let me know how can I format this command to do what i intend to do.

You can use subprocess.check_output with shell=True:

import subprocess

print(subprocess.check_output(["df -g | grep -w /"], shell=True).split()[2])

.split() splits the return into the separate values, and then [2] gets the value that you want.
