Python - 从字典列表中删除具有空值的字典

Question

我想删除具有空值的字典元素列表。

所以以下：

dict = [{"end": "00:15", "item": "Paul Test 1", "start": "00:00"}, {"end": "00:14", "item": "Paul Test 2 ", "start": "00:30"}, {"end": "", "item": "", "start": ""}, {"end": "", "item": "", "start": ""}, {"end": "", "item": "", "start": ""}] 

将返回一个新的字典：

[{"end": "00:15", "item": "Paul Test 1", "start": "00:00"}, {"end": "00:14", "item": "Paul Test 2 ", "start": "00:30"}] 

我已经试过：

{k:v for k,v in dict if not v} 

，但我发现：

ValueError: too many values to unpack (expected 2) 

Answer 1

试试这个：

print([d for d in arr if all(d.values())]) 

不要使用dict的名字：您覆盖Python的一个。在你的情况下，它不是一本字典，它是一组字典。
