Python / Pandas 使用 Yahoo Issue 的 pandas-datareader 读取数据

Question

FutureWarning: pandas.util.testing is deprecated. Use the functions in the public API at pandas.testing instead.

My packages are up-to-date currently but still get the same error above. It'd be great to hear any advice how am I gonna solve the issue.

Answer 1

That was depreciated a couple years ago. Please try it this way.

tickers = ['MMM',
'ABT',
'ABBV',
'ABMD',
'ACN',
'ATVI']

thelen = len(tickers)

price_data = []
for ticker in tickers:
    prices = wb.DataReader(ticker, start = start, end = end, data_source='yahoo')[['Open','Adj Close']]
    price_data.append(prices.assign(ticker=ticker)[['ticker', 'Open', 'Adj Close']])

#names = np.reshape(price_data, (len(price_data), 1))

names = pd.concat(price_data)
names.reset_index()
