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 对象的频率从秒更改为分钟频率,请使用 **period.asfreq()** 方法并设置参数 **'T'**。
首先,导入所需的库 -
import pandas as pd
pandas.Period 表示一段时间。创建 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)
显示具有秒频率的 Period 对象
print("Period...\n", period)
将 Period 从秒转换为分钟频率。我们使用 asfreq() 设置 "T" 将秒转换为分钟频率
res = period.asfreq('T')
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 = 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
这将生成以下代码
Period... 2021-09-11 08:20:45 Final result after converting frequency ... 2021-09-11 08:20
