我希望你能幫我解決這個問題

Answer 1

使用print(json.dumps(r, indent=4))你可以看到結構是

{
    "parkeerlocaties": [
        {
            "parkeerlocatie": {
                "title": "Fietsenstalling Tolhuisplein",
                "Locatie": "{\"type\":\"Point\",\"coordinates\":[4.9032801,52.3824545]}",
                 ...
            }
        },
        {
            "parkeerlocatie": {
                "title": "Fietsenstalling Paradiso",
                "Locatie": "{\"type\":\"Point\",\"coordinates\":[4.8833735,52.3621851]}",
                 ...
            }
        },

因此要訪問內部屬性，您需要遵循 JSON 路徑

import requests
url = ' http://open.data.amsterdam.nl/ivv/parkeren/locaties.json'
search = requests.get(url).json()
for parkeerlocatie in search["parkeerlocaties"]:
    content = parkeerlocatie['parkeerlocatie']
    print(content['title'])
    print(content['adres'])
    print(content['postcode'])
    print()
