Python Pandas - 将给定 Period 对象的频率从秒更改为分钟频率
要将给定Period对象的频率从Seconds更改为Minutely频率，请使用该方法并设置参数'T'。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。我们使用“freq”参数将频率设置为秒，即“S”
period = pd.Period(freq="S", year = 2021, month = 9, day = 11, hour = 8, minute = 20, second = 45)
以秒频率显示Period对象
print("Period...\n", period)将周期从秒转换为分钟频率。我们已经设置了“T”以使用将秒数转换为分钟频率asfreq()
res = period.asfreq('T')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 = 9, day = 11, hour = 8, minute = 20, second = 45)
#displaythePeriodobjectwithSecondsfrequency
print("Period...\n", period)
#ConvertPeriodfromSecondstoMinutelyfrequency
# We have set the "T" to convert seconds to minutely frequency using asfreq()
res = period.asfreq('T')
#displaytheresultafterconversionfromSecondstoMinutelyfrequency
print("\nFinal result after converting frequency ...\n", res)输出结果这将产生以下代码
Period... 2021-09-11 08:20:45 Final result after converting frequency ... 2021-09-11 08:20
