我嵌套了JSON，该JSON是我从需要解析一些信息的网页上检索到的，JSON格式为：

我需要的信息是：arrivalAirport ( CountryName) , departureDate and arrivalDate and from the summary the summary":{"price":
我尝试过类似的事情：
for valori in output['fares']:
print(valori["outbound"])
for notizie in valori["outbound"]:
print(notizie['sellKey'])
但不起作用。我该怎么办？
