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')
以下是代码
import pandas as pd # Thepandas.Periodrepresents a period of time # Creating a Period object # 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) # display the Period object with Seconds frequency print("Period...\n", period) # Convert Period from Seconds to Minutely frequency # We have set the "T" to convert seconds to minutely frequency using asfreq() res = period.asfreq('T') # display the result after conversion from Seconds to Minutely frequency 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
