Python Pandas - 将给定 Period 对象的频率从秒更改为每日频率
要将给定 Period 对象的频率从 Seconds 更改为 Daily 频率,请使用该方法并设置参数“D”。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日频率。我们已设置“D”以使用将秒数转换为每日频率asfreq()
res = period.asfreq('D')
示例
以下是代码
import pandas as pd输出结果# 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 = 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)
这将产生以下代码
Period...2021-04-16 02:35:15
Final result after converting frequency ...
2021-04-16
