Set env and run command
examples/os/set_env.py
import os os.system("echo hello") os.system("echo $HOME") os.system("echo Before $MY_TEST") os.environ['MY_TEST'] = 'qqrq' os.system("echo After $MY_TEST")
We can change the environment variables and that change will be visible in subprocesses,
but once we exit from ou Python program, the change will not persist.
