Read nested data from json using .proto in python - json

Question

I want to read nested data from a json. I have created a .proto file based on the json but still I am not able to read nested data from this said json.
nested.proto --> compiling using protoc --python_out=$PWD nested.proto
syntax = "proto2";
message Employee{
required int32 EMPLOYEE_ID = 1;
message ListItems {
required string FULLADDRESS = 1;
}
repeated ListItems EMPLOYEE_ADDRESS = 2;
}
nested.json
{
"EMPLOYEE_ID": 5044,
"EMPLOYEE_ADDRESS": [
{
"FULLADDRESS": "Suite 762"
}
]
}
parse.py
#!/usr/bin/env python3
import json
from google.protobuf.json_format import Parse
import nested_pb2 as np
input_file = "nested.json"
if __name__ == "__main__":
# reading json file
f = open(input_file, 'rb')
content = json.load(f)
# initialize emp_table here
emp_table = np.Employee()
employee = Parse(json.dumps(content), emp_table, True)
print(employee.EMPLOYEE_ID) #output: 5044
emp_table = np.Employee().ListItems()
items = Parse(json.dumps(content), emp_table, True)
print(items.FULLADDRESS) #output: NO OUTPUT (WHY?)

Answer 1

Couple of things:
The type is ListItems but the name is EMPLOYEE_ADDRESS
Python is awkward (!) with repeated's
You're writing more code than you need
I recommend adhering to the style guide if you can.
Try:
#!/usr/bin/env python3
import json
from google.protobuf.json_format import Parse
import nested_pb2 as np
input_file = "nested.json"
if __name__ == "__main__":
# reading json file
f = open(input_file, 'rb')
content = json.load(f)
# initialize emp_table here
emp_table = np.Employee()
employee = Parse(json.dumps(content), emp_table, True)
print(employee.EMPLOYEE_ID) #output: 5044
for item in employee.EMPLOYEE_ADDRESS:
print(item)
