Python从配置文件取值

配置文件Config.py格式如下：

numNature = 9                       # Integer
                                    # NOTE!
padding = True                      # BOOLEAN
numProduct = None                   # Integer / None
prefix = "ST"                       # String / None
numUnit = 6                         # Integer / None
paddingForNumUnicite = False        # BOOLEAN
numExploitantEmetteur = None        # Integer / None
numExploitantDest = None            # Integer / None

useLogFileTimeStamp = False         # BOOLEAN: Option to set DATE_FABRICATION from last modification date of all the log files inside XML.

#### IF ALL THREE OPTIONS ABOVE ARE SET TO None/False,THEN DATE IS RETRIEVED FROM USER SYSTEM CLOCK NO MATTER WHAT #####

useSystemDateForXMLFileName = False    # Operator can choose whether to print the current system date for Xml filename
                                       # If False, we use config, header or log time stamp values for file name instead.
                                       # If system time is used in dateFabrication, it will print the same date,
                                       # regardless of the choice here. Only affects DATE_FABRICATION in xml IF all 
                                       # three options above are set to false.

limitXMLSize = True                    # BOOLEAN: Controls whether the XML number of lines are limited.
                                       # When False, max value does not matter.
                                       # Default/Normal is 'True'

maxXMLSizeInEntries = 100000           # You can adjust this variable to control the maximum number of lines printed
                                       # onto a file. The program will pre-emptively switch to new xml file
                                       # when value exceeds maxXMLSizeInEntries subtracted by last detected line count
                                       # in the latest log file. Only active when limitXMLsize is True.

在test.py中获取配置文件的值：

import re
import struct
import xml.etree.ElementTree as ET
import getopt
import time
import datetime
import fnmatch
import sys

from ctypes import *

import os
#from types import SimpleNamespace #Only for python 3, replace with class SimpleNamespace for python 27

#Python 27 equivalent implementation of SimpleNamespace
class SimpleNamespace:
    def __init__(self, **kwargs):
        self.__dict__.update(kwargs)

    def __repr__(self):
        keys = sorted(self.__dict__)
        items = ("{}={!r}".format(k, self.__dict__[k]) for k in keys)
        return "{}({})".format(type(self).__name__, ", ".join(items))

    def __eq__(self, other):
        return self.__dict__ == other.__dict__

# 读取配置文件
LotItem_dict = {}
lot_item_globals = {}
exec(compile(open(r'Config.py', "rb").read(), r'Config.py', 'exec'), lot_item_globals, LotItem_dict)
CF = SimpleNamespace(**LotItem_dict)


def main(argv):
    print(CF.limitXMLSize);    # 可以将配置项作为属性使用
    if (CF.limitXMLSize):
        print(CF.maxXMLSizeInEntries);


if __name__ == "__main__":
    main(sys.argv[1:])
    pass
