如何从api响应中提取某些部分

Question

Im learning to use the API's and am having trouble pulling one specific part from a Request. Im using the code:

Request('https://api.kucoin.com/v1/open/currencies')

Which returns this:

{"success":true,"code":"OK","msg":"Operation succeeded.","timestamp":1513157553306,"data":{"rates":{"BTC":{"CHF":16406.52,"HRK":105986.66,"MXN":315682.44,"ZAR":225142.48,"INR":1065126.38,"CNY":109471.64,"THB":539369.4,"AUD":21846.03,"ILS":58546.63,"KRW":18012060,"JPY":1877290,"PLN":59102.38,"GBP":12380.19,"IDR":224977080,"HUF":4418661,"PHP":834691.1,"TRY":63315.12,"RUB":974073.68,"HKD":129114.54,"EUR":14057.51,"DKK":104620.46,"USD":16540,"CAD":21224.12,"MYR":67279.75,"BGN":27492.78,"NOK":138107.34,"RON":65134.52,"SGD":22352.15,"CZK":359811.16,"SEK":139630.68,"NZD":23835.79,"BRL":54896.26}},"currencies":[["USD","$"],["EUR","€"],["AUD","$"],["CAD","$"],["CHF","CHF"],["CNY","¥"],["GBP","£"],["JPY","¥"],["NZD","$"],["BGN","лв."],["BRL","R$"],["CZK","Kč"],["DKK","kr"],["HKD","$"],["HRK","kn"],["HUF","Ft"],["IDR","Rp"],["ILS","₪"],["INR","₹"],["KRW","₩"],["MXN","$"],["MYR","RM"],["NOK","kr"],["PHP","₱"],["PLN","zł"],["RON","lei"],["RUB","₽"],["SEK","kr"],["SGD","$"],["THB","฿"],["TRY","₺"],["ZAR","R"]]}}

Process finished with exit code 0

However I only want to pull the price from one part of this response. How would I best go about this.

Answer 1

Response data is json , therefore you can use json module to extract data

>>> import json
>>> data = 'your response data'
>>> jdata = json.loads(data)
>>> jdata['data']['rates']['BTC']
