python - pd.DatetimeIndex.weekday 和 pd.DatetimeIndex.dayofweek 有什么区别

Question

在 pandas datetimeindex 中，dayofweek和 weekday似乎是一样的。他们只是彼此的别名吗？我发现了这些功能 here

Answer 1

根据pandas源码定义的DatetimeIndex，weekday只是dayofweek的别名，所以没有区别。

class DatetimeIndex:
    ...
    dayofweek = _field_accessor('dayofweek', 'dow',
                                "The day of the week with Monday=0, Sunday=6")
    weekday = dayofweek
