In the same way as you are doing as a command line argument:
Code:
def getEnvVarValue(envVar):
    tmpVal = os.getenv(envVar)
    if not tmpVal:
        print("Environment variable: [%s] not set." % (envVar))
        sys.exit(1)
        
    retValue = tmpVal.strip("'") 
    return retValue


Bin=getEnvVarValue('BIN')
mpdCmd="%s/%s/mpd" % (MPI_ROOTDIR, Bin)
mpdtraceCmd="%s/%s/mpdtrace" % (MPI_ROOTDIR, Bin)
mpdtraceCmd2="%s/%s/mpdtrace -l" % (MPI_ROOTDIR, Bin)

I hope it helps!

rabbitmq-env.conf

RABBITMQ-ENV.CONF(5)						  RabbitMQ Server					      RABBITMQ-ENV.CONF(5)

NAME

       rabbitmq-env.conf - default settings for RabbitMQ AMQP server

DESCRIPTION

       /etc/rabbitmq/rabbitmq-env.conf contains variable settings that override the defaults built in to the RabbitMQ startup scripts.

       The file is interpreted by the system shell, and so should consist of a sequence of shell environment variable definitions. Normal shell
       syntax is permitted (since the file is sourced using the shell "." operator), including line comments starting with "#".

       In order of preference, the startup scripts get their values from the environment, from /etc/rabbitmq/rabbitmq-env.conf and finally from
       the built-in default values. For example, for the RABBITMQ_NODENAME setting,

       RABBITMQ_NODENAME

       from the environment is checked first. If it is absent or equal to the empty string, then

       NODENAME

       from /etc/rabbitmq/rabbitmq-env.conf is checked. If it is also absent or set equal to the empty string then the default value from the
       startup script is used.

       The variable names in /etc/rabbitmq/rabbitmq-env.conf are always equal to the environment variable names, with the RABBITMQ_ prefix
       removed: RABBITMQ_NODE_PORT from the environment becomes NODE_PORT in the /etc/rabbitmq/rabbitmq-env.conf file, etc.

       # I am a complete /etc/rabbitmq/rabbitmq-env.conf file.
       # Comment lines start with a hash character.
       # This is a /bin/sh script file - use ordinary envt var syntax
       NODENAME=hare

SEE ALSO

       rabbitmq-server(1) rabbitmqctl(1)

EXAMPLES

       # I am a complete /etc/rabbitmq/rabbitmq-env.conf file.
       # Comment lines start with a hash character.
       # This is a /bin/sh script file - use ordinary envt var syntax
       NODENAME=hare

       This is an example of a complete /etc/rabbitmq/rabbitmq-env.conf file that overrides the default Erlang node name from "rabbit" to "hare".
