英文:
Python format json for saving to file
问题
My data looks like this:
Key1: [Key2:[{},{},...{}]]
The code something like this:
dict_={}
dict_['Key2']=all_items
dict_fin={}
dict_fin['Key1']=[dict_]
df=pd.DataFrame(dict_fin)
df.to_json(filepath, orient="records", lines=True)
I would like to have saved json like this:
{ "Key1": [{"Key2" : [{},{},...,{}]}] }
Instead, I get it like this:
{ "Key1": {"Key2" : [{},{},...,{}]} }

Use the json module from the Python standard library:
import json
outer_dict = {}
some_list = [{"inner_key": "inner_value"}, {"inner_key_2": "inner_value_2"}]
outer_dict["Key1"] = some_list
json.dumps(outer_dict)
Will give you:
'{"Key1": [{"inner_key": "inner_value"}, {"inner_key_2": "inner_value_2"}]}'

I believe the errors is on the line dict_fin['Ke1']=[dict_]. You had assigned dict_['Key2'] instead:
dict_={}
dict_['Key2']=all_items
dict_fin={}
dict_fin['Ke1']=[dict_['Key2']]
df=pd.DataFrame(dict_fin)
df.to_json(filepath, orient="records", lines=True)
