我使用 Python 包yfinance
来获取股票的历史股价(在本例中为特斯拉的股票)。
当我执行以下操作并以一分钟间隔获取上周的股票价格时:
import yfinance as yf
print(yf.Ticker('TSLA').history(period='7d', interval='1m'))
我明白了

所以我可以看到每个时间间隔的日期和时间。
但是,当我改为选择一小时间隔时:
import yfinance as yf
print(yf.Ticker('TSLA').history(period='7d', interval='1h'))

这意味着我不知道不同时间间隔的时间,只是在哪一天记录它们。怎么会?我在选择一分钟间隔时得到一天中的时间,那么为什么我不得到一小时间隔呢?在使用一小时间隔时,我能否以某种方式轻松获得一天中的时间,还是我必须将它们与一分钟间隔进行比较并尝试找出哪个间隔对应于哪个小时?
