您可以随时自定义频率，而不仅仅是1 hour或1 minute。
我想得到一个百分比的速度数据下降到一个范围内的百分比。例如,5%的速度数据在0到5之间,10%在5到10之间,等等。我也希望能够将输出重采样到任何频率(整个周期,每天,每月等)。我有一个看起来像这样的DataFrame: 'datetime':pd.date_range('frequency = 'D ...
date_range(start=None, end=None, periods=None, freq=None, tz=None, normalize=False, name=None, closed=None, **kwargs)Return a fixed frequency DatetimeIndex.
date_range(start=None, end=None, periods=None, freq=None, tz=None, normalize=False, name=None, closed=None, **kwargs) Return a fixed frequency DatetimeIndex. Parameters --- start : str or datetime-like, optional Left bound for generating dates. end : str or datetime-like, optional Right...
pd.date_range(start=None,end=None,periods=None,freq=None) Return a fixed frequency DatetimeIndex. start:表示起始 end:表示结尾 periods:表示时间段 freq:表示有倍数的频率字符串,e.g. '5H'. pd.date_range("2021-8-8", periods=8) # 表示从2021-8-8开始到现在日期的8个时间 ...
