Answer 1

只需使用

import pandas_datareader.data as web

sp500 = web.get_data_yahoo('SPY', start=start, end=end)

Answer 2

该错误是不言自明的。Yahoo API已更改，因此从Yahoo API读取的旧的Pandas代码不再起作用。你读过这个讨论有关API的变化及其对大熊猫的影响？本质上，Pandas无法读取新的Yahoo API，并且将花费很长时间来编写新代码，因此临时解决方案是在ImmediateDeprecationError每次有人尝试将Pandas用于Yahoo API时提出建议。
