I'm not sure what instructions you're following to get what you showed. There is no built-in function called cd or run in Python.
You can call a program in a specific directory using the subprocess module:
import subprocess
subprocess.call("./program", cwd="/home/user/a/b")
The cwd argument causes the call function to automatically switch to that directory before starting the program named in the first argument.

appreciate the speedy help :D
It looks like you are trying to use functionalities of fabric. Make sure fabric is installed, and cd and run are imported from fabric. Something like,
from fabric.context_managers import cd
from fabric.operations import run
import os
os.chdir("/home/user/a/b")
with cd("/home/user/a/b"):
run ("./program")
Save your file as fabfile.py,and from the same directory run it as:
fab -H localhost
For more information on the fabric, checkout: fabric
