filtering a list of dictionary as per given criteria

[jss]

i have metadata and api_request as below.

metadata = [

    {"path": "d/scripts", "name": "../"},
    {"path": "d/scripts", "name": "../"},
    {"path": "d/scripts", "name": "unn_details_in.cfg"},
    {"path": "d/scripts", "name": "unn_details_out.cfg"},
    {"path": "d/scripts", "name": "unn_details_in_v1.cfg"},
    {"path": "d/scripts", "name": "unn_details_out_v1.cfg"},
    {"path": "c/scripts", "name": "./"},
    {"path": "c/scripts", "name": "../"}


]

api_request = {"response_filter": [
    {"path": {"value": "d/scripts"}, "name": {"value": "[a-z_]*details_in[a-z1-2_]*.cfg$", "operator": "match"}},
    {"path": {"value": "d/scripts"}, "name": {"value": "[a-z_]*details_out[a-z1-2_]*.cfg$", "operator": "match"}}
]}

final_list=[]
for details in api_request["response_filter"]:
    for key,value in details.items():
        final_list.extend(
            data
            for data in metadata
            if OPERATION_MAPPER[value.get("operator","eq")](value.get("value"),data[key])


         and data not in final_list)

print(final_list)

i am supposed to iterate api_request["response_filter"] and what ever is the value for path(in this case d/scripts),i need to filter

only that data and in those filtered data , i need to ensure that name should of the mentioned regex.

Requirement:detail_in and detail_out should be present in a given metadata

if the filtered data has both detail_in and detail_out present in name for a given metadata...i should not raise any error.if either

detail_in or detail_out is absent ,i need to raise error and mentioned the error like "detail in not present" or "detailout not present "

i did the following way,but i am not able to proceed further


for the above example of metadata ,there should be no error raised

suppose the metadata is as below

metadata = [

    {"path": "d/scripts", "name": "../"},
    {"path": "d/scripts", "name": "../"},
    {"path": "d/scripts", "name": "unn_details_in.cfg"},
    {"path": "d/scripts", "name": "unn_details_in_v1.cfg"},
    {"path": "c/scripts", "name": "./"},
    {"path": "c/scripts", "name": "../"}


]

we should get the message as details_out absent

waiting for a response.Thank you

What are detail_in and detail_out?

detail_in and detail_out is the substring in the value of key called "name" in the given metadata as shown below

[
 
    {"path": "d/scripts", "name": "../"},
    {"path": "d/scripts", "name": "../"},
    {"path": "d/scripts", "name": "unn_details_in.cfg"},
    {"path": "d/scripts", "name": "unn_details_in_v1.cfg"},
    {"path": "c/scripts", "name": "./"},
    {"path": "c/scripts", "name": "../"}
 
 
]

i need to check if a given list of metadata contains detail_in and detail_out present in the name field.If both the detail_in and detail_out are present in a list of metadata,i should not raise error.If either of them is present and one of them is absent .i need to know which is absent in the error message

You can use the in operator with strings. Note that 'detail_in' is different from 'details_in'

>>> 'details_in' in "unn_details_in_v1.cfg"
True
>>> 'details_in' in "unn_details_out_v1.cfg"
False
>>>
