Python Pandas - 将给定的 Period 对象的频率从秒更改为天
要将给定 Period 对象的频率从秒更改为天,请使用 period.asfreq() 方法并设置参数‘D’。
首先,导入所需的库 -
import pandas as pd
pandas.Period 表示一段时间。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 = 4, day = 16, hour = 2, minute = 35, second = 15)
显示以秒为频率的 Period 对象
print("Period...\n", period)
将 Period 从秒转换为天。我们使用 asfreq() 将“D”设置为按天转换
res = period.asfreq('D')
示例
以下是代码
import pandas as pd # The pandas.Period represents 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 = 4, day = 16, hour = 2, minute = 35, second = 15) # display the Period object with Seconds frequency print("Period...\n", period) # Convert Period from Seconds to Daily frequency # We have set the "D" to convert seconds to daily frequency using asfreq() res = period.asfreq('D') # display the result after conversion from Seconds to Daily frequency print("\nFinal result after converting frequency ...\n", res)
输出
这将生成以下代码
Period... 2021-04-16 02:35:15 Final result after converting frequency ... 2021-04-16
