Question

A network engineer writes a Python script that uses the requests library to pull device inventory from Cisco Catalyst Center. The relevant lines are:

resp = requests.get(url, headers=hdr, verify=False)
    if resp.status_code == 200:
        data = resp.json()
        for d in data['response']:
            print(d['hostname'])

When run, the script prints nothing and raises no exception. The engineer confirms the token is valid and the URL is correct. Inspecting the raw response shows an HTTP 200 with a body of {"response": []}. What does this behavior indicate?

Accepted Answer

The request succeeded but the API returned an empty result set, so the for loop had nothing to iterate over.

Answer

The status_code comparison failed because requests returns status codes as strings, not integers.

Answer

The token is expired; Catalyst Center silently returns 200 with an empty body when authentication fails.

Answer

resp.json() raised a decoding error that was suppressed, so data was never populated.
