import os

confdir = os.getenv("my_config") # Set the variable confdir from the OS environment variable

conffile = 'env_check.conf' # Set the variable conffile

conffilename = os.path.join(confdir, conffile) # Set the variable conffilename by joining confdir and conffile together

for env_check in open(conffilename): # Open the config file and read all the settings

env_check = env_check.strip() # Set the variable as itsself, but strip the extra text out

print '[{}]'.format(env_check) # Format the Output to be in Square Brackets

newenv = os.getenv(env_check) # Set the variable newenv to get the settings from the OS what is currently set for the settings out the configfile

if newenv is None: # If it doesn't exist

print env_check, 'is not set' # Print it is not set

else: # Else if it does exist

print 'Current Setting for {}={}\n'.format(env_check, newenv) # Print out the details
