<p>我有一个与json数据的链接,我想从中将数据分离为两个数据帧</p>
<p>我的代码如下:</p>
<pre><code>import pandas as pd
import requests
pd.set_option('display.max_rows', 50000)
pd.set_option('display.max_columns', 100)
pd.set_option('display.width', 10000)
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.163 Safari/537.36'}
url = "https://www.nseindia.com/api/option-chain-indices?symbol=BANKNIFTY"
data = requests.get(url, headers=headers).json()
for x in range(len(data['records']['data'])):
print(data['records']['data'][x])
</code></pre>
<p>输出包含如下所示的行,其中“CE”&;“PE”数据可用:</p>

<p>我想储存CE&;列名称为的两个单独数据框中的PE值</p>
<pre><code>['strikePrice','expiryDate', 'underlying', 'identifier', 'openInterest', 'changeinOpenInterest', 'pchangeinOpenInterest', 'totalTradedVolume','impliedVolatility', 'lastPrice', 'change', 'pChange', 'totalBuyQuantity', 'totalSellQuantity', 'bidQty', 'bidprice', 'askQty', 'askPrice', 'underlyingValue']
