如何删除字典列表中的空字典？

尝试这个

In [50]: mydict = {
   ....:  "ages":[{"age":25,"job":"teacher"},
   ....:          {},{},
   ....:          {"age":35,"job":"clerk"}
   ....:         ]
   ....: }

In [51]: mydict = {"ages":[i for i in mydict["ages"] if i]}

In [52]: mydict
Out[52]: {'ages': [{'age': 25, 'job': 'teacher'}, {'age': 35, 'job': 'clerk'}]}

或简单地使用filter

>>>mylist = [{'age': 25, 'job': 'teacher'}, {}, {}, {'age': 35, 'job': 'clerk'}]
>>>filter(None, mylist)
[{'age': 25, 'job': 'teacher'}, {'age': 35, 'job': 'clerk'}]

因此，在您的字典中，将其应用为

{
 "ages":filter(None, [{"age":25,"job":"teacher"},
         {},{},
         {"age":35,"job":"clerk"}
        ])
}
