accessing variables in Ini files from python

import sys
import linuxcnc

inifile = linuxcnc.ini(sys.argv[1])

# inifile.find() returns None if the key wasnt found - the
# following idiom is useful for setting a default value:

machine_name = inifile.find('EMC', 'MACHINE') or "unknown"
print "machine name: ", machine_name

# inifile.findall() returns a list of matches, or an empty list
# if the key wasnt found:

extensions = inifile.findall("FILTER", "PROGRAM_EXTENSION")
print "extensions: ", extensions

# override default NML file by ini parameter if given
nmlfile = inifile.find("EMC", "NML_FILE")
if nmlfile:
    linuxcnc.nmlfile = os.path.join(os.path.dirname(sys.argv[1]), nmlfile)
