Python Pandas - 将给定的 Period 对象的频率从秒更改为小时频率
要将给定 Period 对象的频率从秒更改为小时频率,请使用 period.asfreq() 方法并设置参数“H”。
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' 参数设置频率为秒,即 'S'
period = pd.Period(freq="S", year = 2021, month = 4, day = 16, hour = 2, minute = 35, second = 15)
显示具有秒频率的 Period 对象
print("Period...\n", period)将 Period 从秒转换为小时频率。我们使用 asfreq() 将秒转换为小时频率,并将其设置为“H”
res = period.asfreq('H')
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 Hourly frequency
# We have set the "H" to convert seconds to hourly frequency using asfreq()
res = period.asfreq('H')
# display the result after conversion from Seconds to hourly frequency
print("\nFinal result after converting frequency ...\n", res)输出
这会生成以下代码
Period... 2021-04-16 02:35:15 Final result after converting frequency ... 2021-04-16 02:00
