Python Pandas - 将周期转换为所需的频率
要将 Period 转换为所需频率,请使用方法。假设我们将使用“H”说明符设置为所需的每小时频率。period.asfreq()
首先,导入所需的库 -
import pandas as pd
的pandas.Period代表的一段时间。创建两个 Period 对象
period1 = pd.Period("2020-09-23 03:15:40")period2 = pd.Period(freq="D", year = 2021, month = 4, day = 16, hour = 2, minute = 35)
显示期间对象
print("Period1...\n", period1)print("Period2...\n", period2)
将周期转换为所需频率。我们将频率设置为 H 即每小时频率
res1 = period1.asfreq('H')res2 = period2.asfreq('H')
示例
以下是代码
import pandas as pd输出结果# Thepandas.Periodrepresents a period of time
# creating two Period objects
period1 = pd.Period("2020-09-23 03:15:40")
period2 = pd.Period(freq="D", year = 2021, month = 4, day = 16, hour = 2, minute = 35)
# display the Period objects
print("Period1...\n", period1)
print("Period2...\n", period2)
# Convert Period to desired frequency
# We have set frequency as H i.e. Hourly frequency
res1 = period1.asfreq('H')
res2 = period2.asfreq('H')
# Return the year from the two Period objects
print("\nResult after conversion from the 1st Period object ...\n", res1)
print("\nResult after conversion from the 2nd Period object...\n", res2)
这将产生以下代码
Period1...2020-09-23 03:15:40
Period2...
2021-04-16
Result after conversion from the 1st Period object ...
2020-09-23 03:00
Result after conversion from the 2nd Period object...
2021-04-16 23:00
