如何将类型“ <class'foldername.modulename.functionname'=”“>”转换为python中的字典

Question

我是python的新手，想使用字典值编写XML文件。

当我将字典分配给变量并按如下所述使用dicttoxml时，我可以编写xml文件。

My_Dict = {'data': [{'entity_id': '123456',
           'layout': [{u'database': {u'id': abc
                                     u'name': u'aaa abc
                       u'section': {u'id': u'abc123',
                                    u'name': u'MYSTRING'},
                       u'seriesCode': u'SR11111',
                       u'table': {u'id': u'TB98765',
                                  u'name': u'STRING \u1111 STRING\u2000'},
                       u'topic': {u'id': u'TP890762',
                                  u'name': u'Zee-STRING(Name)'}}],
           'metadata': {'classification': ONE,
                        'country': {'id': 'YYY', 'name': 'ABC'},
                        'end_date': datetime.date(2019, 11, 02),
                        'frequency': {'id': 'YYYY', 'name': 'string'},
                        'id': 123456,
                        'indicator': one,
                        'key_series': one
                        'last_change': {'is_infinity': one
                                        'is_opposite': one
                                        'value': -87},
                        'last_update_time': datetime.datetime(2000, 05, 12, 10, 8, 46, tzinfo=tzutc()),
                        'last_value': 77777777,
                        'multiplier_code': 'OP',
                        'name': 'Abc Defg',
                        'new_series': one,
                        'number_of_observations': 19,
                        'period_end': 00,
                        'province': None,
                        'source': {'country_id': one,
                                   'id': 'YYY-ABC
                                   'name': 'ABC DEF IGK'},
                        'start_date': datetime.date(1983, 20, 05),
                        'status': {'id': 'K', 'name': 'Inactive'},
                        'unit': {'id': '200056', 'name': 'PQR pp'}},
           'subscribed': one,
           'time_points': one,
           'ui': one}

dicttoxml.dicttoxml( My_Dict , attr_type=False, root=True)

但是当我执行另一个SDK文件时，上面的字典值将生成，并且它的类型不是dict。生成值的类型为

<class 'FileName.FolderName.Classname.FucntionName'>

如果我将结果转换为str并尝试将str-> dic转换为

xml_data = dicttoxml.dicttoxml( str(My_dict), attr_type=False, root=True )

我遇到以下错误。

Traceback (most recent call last): 
    xml_data = dicttoxml.dicttoxml( str(xmltext), attr_type=False, root=True )

File "C:\Python27\lib\site-packages\dicttoxml.py", line 393, in dicttoxml
    convert(obj, ids, attr_type, item_func, cdata, parent=custom_root), 
  File "C:\Python27\lib\site-packages\dicttoxml.py", line 177, in convert
    return convert_kv(item_name, obj, attr_type, cdata)
  File "C:\Python27\lib\site-packages\dicttoxml.py", line 334, in convert_kv
    attrstring = make_attrstring(attr)
  File "C:\Python27\lib\site-packages\dicttoxml.py", line 117, in make_attrstring
    attrstring = ' '.join(['%s="%s"' % (k, v) for k, v in attr.items()])
AttributeError: 'bool' object has no attribute 'items'

请帮助我，如何解决此错误。
