headers = CaseInsensitiveDict()
headers["user-agent"] = "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.69 Safari/537.36"

resp = requests.get(url, headers=headers)
json = resp.json()
listings = json["listings"]
print(listings["id"])

output

Traceback (most recent call last): File "main.py", line 14, in print(listings["id"]) TypeError: list indices must be integers or slices, not str

CodePudding user response：

This is because listings is a list of dictionaries, not a dictionary. You can use:

listings[0]["id"]

to get the ID of the first listing.

Alternatively, a simple list comprehension gets all IDs:

listing_ids = [listing["id"] for listing in listings]

Which outputs (for example)

['132982950', '844572039', '1154301185', '1825769295', '749762050', '1015551895', '1914007952', '653876816', '1851808554', '884374799', '1475828358', '1143158393', '67794054', '1944788346', '75060683', '639374907', '1729840421', '182868664', '746987097', '1695237351', '1963349071', '731335050', '1998602300', '1454789034', '894446787', '1310523772', '1343425709', '252474315', '790239965', '1169168224', '77072073', '782777064', '1733251429', '76484476', '577511992', '1548295745', '217148692', '778264112', '1192636205', '1084575147', '94264930', '1759842313', '1635270495', '281968428', '1586757783', '934885503', '1993886816', '415912889', '1445742823', '394209616']

CodePudding user response：

first of all: json["listings"] is a list second of all: you must iterate over the list:

listings = json["listings"]
for listing in listings:
    print(listing["id"])

done
