python - sys.path vs. $PATH

I would like to access the $PATH variable from inside a python program. My understanding so far is that sys.path gives the Python module search path, but what I want is $PATH the environment variable. Is there a way to access that from within Python?

To give a little more background, what I ultimately want to do is find out where a user has Package_X/ installed, so that I can find the absolute path of an html file in Package_X/. If this is a bad practice or if there is a better way to accomplish this, I would appreciate any suggestions. Thanks!

you can read environment variables accessing to the os.environdictionary

import os

my_path = os.environ['PATH']

about searching where a Package is installed, it depends if is installed in PATH
