eval-jsonpath-elam 0.0.1

Get eval() method Jsonpath by json value

Search for the (string, int, float, bool) value in a json object, and return the jsonpath in a string formatted to use in eval() method.

For example: import json from eval_jsonpath_elam.evalpath import get_jsonpath_by_key

json_data = { 
    "objectKeyNameList": [ 
        {"someBoolKey": False },
        {"someFloatKey": 123456.34 },
        {"someIntKey": 7890 },
        {"someStrKey": "my_search_string" }
    ]
}

json_object = json.loads( json.dumps( json_data ) )
eval_string = get_jsonpath_by_key(json_object, "my_search_string") 
print( eval_string ) # "['objectKeyNameList'][3]['someStrKey']"
print( eval( "json_object" + eval_string ) ) # "my_search_string"

Optional parameters

Note: bool, int, float, complex data types will be automatically converted to strings during search. returned_json_path_string will return a string of the json path if found, otherwise the None object will be returned. Search string is case sensitive.
