我有这个 Json，我需要一个费率值。
"_id" : ObjectId("5addb57d0043582d48ba898a"),
"success" : true,
"timestamp" : 1524477784,
"base" : "EUR",
"date" : "2018-04-23",
"rates" : {
"AED" : 4.492662,
"AFN" : 85.576329,
"ALL" : 128.39508,
"AMD" : 586.837094,
"ANG" : 2.177608,
"AOA" : 267.092358,
"ARS" : 24.678283,
"AUD" : 1.602032,
"AWG" : 2.177639,
"AZN" : 2.079155,
"BAM" : 1.958775,
"BBD" : 2.446786,
"BDT" : 101.517146,
"BGN" : 1.943843,
"BHD" : 0.460968,
"NOK" : 9.626194,
}
这是我的 Python 代码
import pymongo
uri = "mongodb://127.0.0.1:27017"
client = pymongo.MongoClient(uri)
database = client['db']
collection = database['currency']
collection2 = database['countries']
p = str(input('Insert the country: ')).capitalize()
if p=='Norway':
currency = collection.find_one({'NOK'})
print(currency)
我想打印de NOK里面的值，我该怎么做？ 提前致谢。
最佳答案
我认为你可以通过以下方式调用它:
currency = collection.find_one({"NOK"})
print(currency['rates']['NOK'])
