如何在Python中解析YAHOO.Finance.SymbolSuggest.ssCallback的结果

Question

我正在使用Python 3，并尝试使用YAHOO.Finance.SymbolSuggest.ssCallback从公司名称中获取可能的股票符号列表

使用下面的代码

import urllib

yahoo_url = 'http://d.yimg.com/autoc.finance.yahoo.com/autoc?query=apple+inc&region=1&lang=en&callback=YAHOO.Finance.SymbolSuggest.ssCallback'

response = urllib.request.urlopen(yahoo_url)

str_response = response.read().decode('utf-8')

结果如下：

str_response
Out[136]: 'YAHOO.Finance.SymbolSuggest.ssCallback({"ResultSet":{"Query":"AAPL","Result":[{"symbol":"AAPL","name":"Apple Inc.","exch":"NMS","type":"S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"^NY2LAAPL","name":"ICE Leveraged 2x AAPL Index","exch":"NYS","type":"I","exchDisp":"NYSE","typeDisp":"Index"},{"symbol":"AAPL.BA","name":"Apple Inc.","exch":"BUE","type":"S","exchDisp":"Buenos Aires","typeDisp":"Equity"},{"symbol":"AAPL34.SA","name":"Apple Inc.","exch":"SAO","type":"S","exchDisp":"Sao Paolo","typeDisp":"Equity"},{"symbol":"AAPL.MX","name":"Apple Inc.","exch":"MEX","type":"S","exchDisp":"Mexico","typeDisp":"Equity"},{"symbol":"AAPL.MI","name":"APPLE","exch":"MIL","type":"S","exchDisp":"Milan","typeDisp":"Equity"},{"symbol":"AAPLD.BA","name":"APPLE INC","exch":"BUE","type":"S","exchDisp":"Buenos Aires","typeDisp":"Equity"},{"symbol":"AAPLC.BA","name":"APPLE INC","exch":"BUE","type":"S","exchDisp":"Buenos Aires","typeDisp":"Equity"},{"symbol":"AAPL.VI","name":"Apple Inc.","exch":"VIE","type":"S","exchDisp":"Vienna","typeDisp":"Equity"}]}});'

如何仅提取以下段？然后写进字典

"Result":[{"symbol":"AAPL","name":"Apple Inc.","exch":"NMS","type":"S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"^NY2LAAPL","name":"ICE Leveraged 2x AAPL Index","exch":"NYS","type":"I","exchDisp":"NYSE","typeDisp":"Index"},{"symbol":"AAPL.BA","name":"Apple Inc.","exch":"BUE","type":"S","exchDisp":"Buenos Aires","typeDisp":"Equity"},{"symbol":"AAPL34.SA","name":"Apple Inc.","exch":"SAO","type":"S","exchDisp":"Sao Paolo","typeDisp":"Equity"},{"symbol":"AAPL.MX","name":"Apple Inc.","exch":"MEX","type":"S","exchDisp":"Mexico","typeDisp":"Equity"},{"symbol":"AAPL.MI","name":"APPLE","exch":"MIL","type":"S","exchDisp":"Milan","typeDisp":"Equity"},{"symbol":"AAPLD.BA","name":"APPLE INC","exch":"BUE","type":"S","exchDisp":"Buenos Aires","typeDisp":"Equity"},{"symbol":"AAPLC.BA","name":"APPLE INC","exch":"BUE","type":"S","exchDisp":"Buenos Aires","typeDisp":"Equity"},{"symbol":"AAPL.VI","name":"Apple Inc.","exch":"VIE","type":"S","exchDisp":"Vienna","typeDisp":"Equity"}]

先谢谢你

Answer 1

将字符串转换为dict

• 使用^{}

from ast import literal_eval

result = literal_eval(str_response[39:-2])

print(type(result))
>>> dict

# Result key of interest
Result = result['ResultSet']['Result']

print(Result)
