Calling a Returned Value to Another Function

[valerydolce]

Hi Gigs,

I'm trying to call a value obtained from a function to another function. In this case, i want to call var_name into get_dirs_from_path() function.
Below is what i did, but it's not working.
NB:  get_dirs_from_path()  must not have a parameter.

#! /usr/bin/python3

import os
import sys

def get_environment_variable_value(variable_name):
    var_name = os.environ[variable_name]
    if not var_name:
        return ""
    else:
        return var_name

def get_dirs_from_path():
    path_var = var_name
    directories = path_var.split(':')
    for entry in directories:
        print (entry)

Please advise.
