pandas.DataFrame.resample()重新采样时间序列数据

重新采样时间序列数据

频率转换和时间序列重采样的便捷方法。对象必须具有类似datetime的索引（DatetimeIndex， PeriodIndex或TimedeltaIndex），或将类似datetime的值传递给on或level关键字

DataFrame.resample(rule, axis=0, closed=None, label=None, convention='start', kind=None, loffset=None, base=None, on=None, level=None, origin='start_day', offset=None)[source]

参数：

rule：DateOffset, Timedelta or str，

axis：{0 or ‘index’, 1 or ‘columns’}, default 0，

closed：{‘right’, ‘left’}, default None

label：{‘right’, ‘left’}, default None

convention：{‘start’, ‘end’, ‘s’, ‘e’}, default ‘start’

kind：{‘timestamp’, ‘period’}, optional, default None

loffset：timedelta, default None

base：int, default 0

on：str, optional

level：str or int, optional

origin：{‘epoch’, ‘start’, ‘start_day’}, Timestamp or str, default ‘start_day’

offset：Timedelta or str, default is None
