我有一个if语句，它检查它是否为"；列表"；。如果是这样的话，不要把它作为类型列表放在字典中，而是把它放在原始位置，因为它已经是一个列表了。(保存到字典中(
对于其他元素，按应分配元素(保存到字典中(
然而，if语句似乎从未执行
请参阅下面提到的代码部分，
print(type(contentAggregator[8]))
print(type(contentAggregator[9]))
print(type(contentAggregator[10]))
for i, k in enumerate(contentDict):
if type(contentAggregator[i]) == isinstance(contentAggregator[i],list):
contentDict[k] = contentAggregator[i]
else:
contentDict[k] = [contentAggregator[i]]
print(contentAggregator)
print(contentDict)
上面的代码进行了检查，我已经验证了元素的类型是"list"，但由于某种原因，我的if语句似乎从未执行过。真正棘手的。。。

type返回传递给它的参数的类型对象。isinstance返回一个布尔值，描述第一个参数是否是第二个参数的实例。他们永远不可能是平等的。长话短说，去掉type表达式，只计算isinstance表达式：
if isinstance(contentAggregator[i], list):
