无法在 Pandas 中保存值

Question

我能够看到收报机收到了数据，但我无法将其写入 pandas 文件 df。

stock_data = []
with open('Nifty 50 Scrapped data.csv') as csvfile:
    stockticker_data = csv.reader(csvfile, delimiter=' ')
    for row in stockticker_data:
        print(row)

        for ticker in row:
            stock_data.append(web.get_data_yahoo(ticker, '1/1/2018', '1/1/2019'))
            # stock_data.append(all_data)
            df = pd.DataFrame(stock_data)
            print(df)

如果我 print(stock_data) 而不是 print(df) 我得到以下输出：

这是我想要的，但是 df = pd.DataFrame(stock_data) print(df) 的输出是

['ASIANPAINT.NS']
                                                   0

为什么这里没有显示数据？

Answer 1

stock_data = []
with open('Nifty 50 Scrapped data.csv') as csvfile:
    stockticker_data = csv.reader(csvfile, delimiter=' ')
    for row in stockticker_data:
        print(row)

        for ticker in row:
            stock_data.append(web.get_data_yahoo(ticker,'1/1/2018','1/1/2019'))
            # stock_data.append(all_data)
df = pd.DataFrame(stock_data)
print(df)

试试这个，也许那个循环会弄乱你的 df
