Python Pandas - 将给定 Period 对象的频率从秒更改为每小时频率
要将给定Period对象的频率从Seconds更改为Hourly频率，请使用该方法并设置参数“H”。period.asfreq()
首先，导入所需的库-
import pandas as pd
的pandas.Period代表的一段时间。创建一个Period对象。我们已将频率设置为秒，即。'S'使用'freq'参数
period = pd.Period(freq="S", year = 2021, month = 4, day = 16, hour = 2, minute = 35, second = 15)
以秒频率显示Period对象
print("Period...\n", period)将周期从秒转换为每小时频率。我们已经设置了“H”以使用将秒数转换为小时频率asfreq()
res = period.asfreq('H')示例
以下是代码
import pandas as pd
#Thepandas.Periodrepresentsaperiodoftime
#CreatingaPeriodobject
# We have set the frequency as seconds ie. 'S' using the 'freq' parameter
period = pd.Period(freq="S", year = 2021, month = 4, day = 16, hour = 2, minute = 35, second = 15)
#displaythePeriodobjectwithSecondsfrequency
print("Period...\n", period)
#ConvertPeriodfromSecondstoHourlyfrequency
# We have set the "H" to convert seconds to hourly frequency using asfreq()
res = period.asfreq('H')
#displaytheresultafterconversionfromSecondstohourlyfrequency
print("\nFinal result after converting frequency ...\n", res)输出结果这将产生以下代码
Period... 2021-04-16 02:35:15 Final result after converting frequency ... 2021-04-16 02:00
