<p>我有下面的函数，它提取一些数据，然后尝试将每个数据存储在字典<code>tickerdata</code>中各自的位置。字典的每个值都是另一个字典。但是，第一个内部字典（key=“MMM”）的值被设置为字典其余部分的值。我不确定如何解决这个问题</p> <pre><code>def scandata(volumelimita, volumelimitb, lastchangelimita,lastchangelimitb, ivlimita, ivlimitb): tickers = save_sp500_tickers() tickerdata = {key: {} for key in tickers} keydefine = {"price":0, "volume":0, "netchange":0, "iv":0} tickerdata = {key: keydefine for key in tickers} for i in range(100): #print("increment is "+str(i)) stock = tickers[i] try: if((fetchstock(stock)['totalVolume']>volumelimita) and (fetchstock(stock)['totalVolume']< volumelimitb) and (fetchstock(stock)['netChange']>lastchangelimita) and (fetchstock(stock)['netChange']< lastchangelimitb)
