法律研究Python Pandas - 获取给定周期对象的频率
要获取指定周期对象的频率，请使用 period.freq 属性。
首先，导入所需的库 −
import pandas as pd
pandas.Period 表示一个时间段。创建两个 Period 对象 −
period1 = pd.Period("2020-09-23 03:55:20")
period2 = pd.Period(freq="T", year = 2021, month = 2, day = 14, hour = 2, minute = 35)显示 Period 对象 −
print("Period1...\n", period1)
print("Period2...\n", period2)从两个 Period 对象获取频率 −
res1 = period1.freq res2 = period2.freq
示例
以下为代码 −
import pandas as pd
# The pandas.Period represents a period of time
# creating two Period objects
period1 = pd.Period("2020-09-23 03:55:20")
period2 = pd.Period(freq="T", year = 2021, month = 2, day = 14, hour = 2, minute = 35)
# display the Period objects
print("Period1...\n", period1)
print("Period2...\n", period2)
# get the frequency from two Period objects
res1 = period1.freq
res2 = period2.freq
# Return the frequency from two Period objects
print("\nDisplay the frequency from the 1st Period object ...\n", res1)
print("\nDisplay the frequency from the 2nd Period object ...\n", res2)输出
这将产生以下代码 −
Period1... 2020-09-23 03:55:20 Period2... 2021-02-14 02:35 Display the frequency from the 1st Period object ... <Second> Display the frequency from the 2nd Period object ... <Minute>
