Question

我有工具，用于生成和显示配置（部分）。

INI文件看起来像：

...

[test]
MATH_DLL = 035f210e-6c06-4021-8857-0759409c4bb7
MATH_DLL_XML = 805fe0f0-2627-4ced-bac5-8725ef9839ef
ASSETMANAGER_API_DLL = 426d1824-628f-47ed-8539-4a0ed292b94e
...

我现在想要的 - 添加选项以删除＆＃34; main＆＃34;文件：

...
parser_unity.add_argument('-x', '--remove', action='store', dest='unity_uuid_remove',
                          help='Remove configuration from uuids.ini. Must be called with config_name to delete')
...

和

def handler_unity(action_list):
...
    if action_list.unity_uuid_remove:
        from lib.unity.uuidgen import UuuidManagment
        u = UuuidManagment(logger, RDS_BASEDIR)
        u.config_remove(action_list.unity_uuid_remove)

课程和方法：

class UuuidManagment(object):

    """Class for data in uuids.ini file management"""

    def __init__(self, logger, rds_basedir):

        self.config = ConfigParser.ConfigParser()
        self.config_file = os.path.join(rds_basedir, 'conf', 'unity', 'uuids.ini')
        self.config.read(self.config_file)
        self.configs = self.config.sections()

        self.logger = logger
        self.rds_basedir = rds_basedir

    ...

    def config_remove(self, config_name):

        """Remove config_name specified in argument from uuids.ini"""

        self.logger.logger.info('Remove %s' % config_name)

        print(self.config, self.configs, config_name)

        self.config.remove_section(config_name)

        with open(self.config_file, 'r+') as out:
            self.config.write(out)

但它不想工作。

目前的配置：

d:\RDS\rdsmanager>RDSmanager.py unity -l

删除它：

Answer 1

在config_remove中，您以r+模式打开文件。

您应该以write / truncate模式w打开它以正确地重写文件，如doc中所示。

'w'用于写入（如果文件已存在则截断文件）

有关详情，请提出以下问题：Confused by python file mode “w+”与+变种的实际目的相关。

ConfigParser - remove_section不删除部分
