Get LINUX env variable with python

Question

I have my ~/.bashrc file:

PATH=$PATH:/usr/pgsql-9.3/bin/

DB_USER=postgres
DB_PASSWORD=password
DB_HOST=localhost

When I'm doing os.environ['PATH'] I get :

/usr/local/sbin

But when I'm doing os.environ['DB_USER'] I get:

KeyError: 'DB_USER'

How I need to declare my vars correctly for python, cause echo in shell :

echo $DB_USER
    >>> postgres

thanx

You haven't exported your variables:

export DB_USER=postgres
export DB_PASSWORD=password
export DB_HOST=localhost

if you get /usr/local/sbin from os.environ['PATH'] this is an indication your .bash.rc did not run since you change the PATH there in the first line.

Any chance you did not restart bash before checking this?
