Python/Pycharm：用于循环获取字符串而不是字典

Question

我是 python 新手，所以这似乎是一个非常愚蠢的问题，请多多包涵。

我正在使用以下代码： （如果还附上调试图像）

for connector in la_details['properties']['parameters']['$connections']['value']:
    if connector['connectionName'] in allowed_connectors:
        result = True

现在，它不是在 'connector' 变量中获取 'dict' 值，而是获取一个 'string'，因此 'if' 语句给出了错误：

string indices must be integers

有人可以指导我如何获取“dict”值而不是“string”吗？我试图用谷歌搜索，但找不到任何与这种情况相匹配的东西，可能是因为我使用了错误的术语。

编辑：print(la_details) 产生以下输出：

{u'name': u'REDACTED',
 u'tags': {},
 u'id': u'/subscriptions/REDACTED/resourceGroups/REDACTED/providers/Microsoft.Logic/workflows/REDACTED',

在 python for ... in ... 中，返回列表中的值或字典中的键（如您的示例中所示），以下是执行循环的正确方法。

la_details = {
  'properties': {
    'parameters': {
      '$connections': {
        'value': {
          'office365': { 'connectionName': 'office365' },
          'sql': { 'connectionName': 'sql' },
        }
      }
    }
  }
}

allowed_connectors = ['sql']

#for connector in la_details['properties']['parameters']['$connections']['value']:
#  if connector['connectionName'] in allowed_connectors:
#    return True
#  else:
#    return 'False

values = la_details['properties']['parameters']['$connections']['value']

for connector in values:
  if values[connector]['connectionName'] in allowed_connectors:
    print('{0} is allowed'.format(values[connector]['connectionName']))
  else:
    print('{0} is not allowed'.format(values[connector]['connectionName']))
