我想计算每个indexID的“fv”中的值的数量，并识别（打印输出），然后删除“fv”中的值数量不等于40的indexID。我该怎么做

我知道如何访问字典的值，但不知道如何访问列表中的字典值

更新

not_40 = [d for d in _deFV if len(d['fv']) != 40]
remove_list = []
pos = 0

for x in not_40:
    print "\nThese entries in _deFV will be removed as they do not have 40 features in the feature vetor: \n{}".format(x)
    remove_list.append(int(x['indexID']))

for dic in _deFV:
    if dic['indexID'] == remove_list[pos]:
        pos+=1

---

我可以确定要删除列表中的哪个词汇，但我不确定如何删除。但是，我确实收到了此错误

索引器错误：列表索引超出范围
您可以在数据中找到长度不为40的元素，如下所示：

代码：
测试代码：
结果：
到目前为止，您尝试了什么？如果我想从列表中删除该特定词典，我可以在for循环中使用data.pop（x）吗？
pop
从列表中删除该项并返回该项。如果您只想删除，请使用
remove
@bunbun谢谢！我不知道为什么有人否决了它，因为这段代码对我来说很有用，但它还不完整。我意识到从not_40中删除不是我需要的，因为我需要从原始的_devv中删除该条目。对于这一点，还有其他的列表理解吗？通常我们不主张在遍历列表时修改列表。因此，您只需执行
\u deFV=not_40
@bunbun哦，我的意思是，与其创建一个包含我要删除的所有词典的新词典列表，不如将它们从原始词典列表中删除。这可能吗？
not_40 = [d for d in data if len(d['fv']) != 40]

for x in not_40:
    print(x)
