我发现了一个有趣的观察结果。我写了一个配置文件读取程序,
import ConfigParser
class ConfReader(object):
ConfMap = dict()
def __init__(self):
self.config = ConfigParser.ConfigParser()
self.config.read('./Config.ini')
self.__loadConfigMap()
def __loadConfigMap(self):
for sec in self.config.sections():
for key,value in self.config.items(sec):
print 'key = ', key, 'Value = ', value
keyDict = str(sec) + '_' + str(key)
print 'keyDict = ' + keyDict
self.ConfMap[keyDict] = value
def getValue(self, key):
value = ''
try:
print ' Key = ', key
value = self.ConfMap[key]
except KeyError as KE:
print 'Key', KE , ' didn\'t found in configuration.'
return value
class MyConfReader(object):
objConfReader = ConfReader()
def main():
print MyConfReader().objConfReader.getValue('DB2.poolsize')
print MyConfReader().objConfReader.getValue('DB_NAME')
if __name__=='__main__':
main()
我的 Config.ini 文件看起来像,
[DB]
HOST_NAME=localhost
NAME=temp
USER_NAME=postgres
PASSWORD=mandy
__loadConfigMap() 工作得很好。但是在读取键和值时,它会使键小写。我不明白原因。任何人都可以解释为什么会这样吗?
