ef.stock.get_base_info（）获取多只股票信息报错。

stock_code = ['000001','159949']

df = ef.stock.get_base_info(stock_code)
print(df)

运行后报错如下：

Mac和win环境都测试，报错一样，获取单个股票信息没问题。

Start at efinance/stock/getter.py, especially get_base_info and get_base_info_muliti, then reproduce the reported call with ['000001', '159949']. The fix is complete when retrieving multiple stocks no longer raises KeyError for 股票代码 and still returns the expected dataframe, while single-stock retrieval continues to work.
