Trying to loop from API response need help with nested JSON

Question

I only have a few months of learning python so I don't have much experience.
I'm trying to get results of a API response so I can make another API call. I need to get the portID and system name so I can make the 2nd API call I want. I only need the LLDP information since that has the information I need.
Below I have the first two API calls that I have come up with. I'm having issues with the lldp_results. Since it's nested I don't know how to loop through it.
Below is the script that I have.
import pprint
import meraki
API_KEY = KEY
dashboard = meraki.DashboardAPI(API_KEY)
organization_id = 'ORG-ID'
response = dashboard.organizations.getOrganizationInventoryDevices(
organization_id, total_pages='all', productTypes='switch'
)
for switch in response:
lldp_results = dashboard.devices.getDeviceLldpCdp(
switch['serial']
)
pprint.pprint(lldp_results)
This is the lldp_results information
[{'ports': {'1': {'lldp': {'portId': 'c8:d9:d2:cc:bb:aa', 'sourcePort': '1'}},
'12': {'lldp': {'portId': '50:a4:d0:cc:bb:aa', 'sourcePort': '12'}},
'13': {'lldp': {'portId': '48:21:0b:cc:bb:aa', 'sourcePort': '13'}},
'14': {'lldp': {'portId': '50:a4:d0:cc:bb:aa', 'sourcePort': '14'}},
'15': {'lldp': {'portId': '48:21:0b:cc:bb:aa', 'sourcePort': '15'}},
'3': {'lldp': {'portId': '00:07:32:cc:bb:aa', 'sourcePort': '3'}},
'37': {'cdp': {'address': '10.60.138.82',
'deviceId': 'AABBCCDDEEFF',
'portId': 'Port 1',
'sourcePort': '37'},
'lldp': {'managementAddress': '10.60.138.82',
'portId': 'AABBCCDDEEFF:P1',
'sourcePort': '37',
'systemName': 'AABBCCDDEEFF'}},
'4': {'lldp': {'portId': '50:a4:d0:92:bb:aa', 'sourcePort': '4'}},
'43': {'cdp': {'address': '10.60.138.81',

Answer 1

Try if this works:
import json
llsp_json = json.loads(lldp_results)
for port in llsp_json["ports"]:
print(llsp_json["ports"][n])

Answer 2

Oh, sorry. I mixed up the name of the loop variable.
Try if this works:
import json
llsp_json = json.loads(lldp_results)
for port in llsp_json["ports"]:
print(llsp_json["ports"][port])

Answer 3

The advantage of using the json module is that it allows you to access elements by position, i.e. without knowing the index.

Answer 4

I tried doing this:
lldp_results['ports']['43']['lldp']
and get
{'sourcePort': '43',
'systemName': 'Meraki MR70 - UN1212INDWAP01',
'portId': '0'}
But I don't know how to loop through the numbers after Ports since the numbers change

Answer 5

@Simon Sauter
I added the import json
I tried your suggestion and first got an error when I tried the json.loads. There erros is:
TypeError: the JSON object must be str, bytes or bytearray, not dict
after somg google I then did a lldp_temp = json.dumps(lldp_results) then lldp_json = json.loads
That worked and then I tried with the loop and get this error
NameError Traceback (most recent call last)
Input In [29], in <cell line: 1>()
1 for ports in lldp_json['ports']:
----> 2 print(lldp_json['ports'][n])
NameError: name 'n' is not defined
If I try to print(lldp_json['ports'] this works with no issues

Answer 6

i just went around my problem by creating a object in a loop that contains all the port numbers (12,13,14 …)
