Python Pandas - 返回应用于给定 Period 对象的时间序列频率的字符串别名
pythonpandasserver side programmingprogramming
要返回应用于给定 Period 对象的时间序列频率的字符串别名，请使用 period.freqstr 属性。
首先，导入所需的库 −
import pandas as pd
pandas.Period 代表一段时间。创建两个 Period 对象 −
period1 = pd.Period("2020-09-23 03:55:20")
period2 = pd.Period(freq="Y", year = 2021, month = 2, day = 14, hour = 2,minute = 35)
显示 Period 对象 −
print("Period1...\n", period1)
print("Period2...\n", period2)
获取频率的字符串别名 −
res1 = period1.freqstr res2 = period2.freqstr
示例
以下是代码 −
import pandas as pd
# pandas.Period 表示一段时间
# 创建两个 Period 对象
period1 = pd.Period("2020-09-23 03:55:20")
period2 = pd.Period(freq="Y", year = 2021, month = 2, day = 14, hour = 2,minute = 35)
# 显示 Period 对象
print("Period1...\n", period1)
print("Period2...\n", period2)
# 获取频率的字符串别名
res1 = period1.freqstr
res2 = period2.freqstr
# 从两个 Period 对象返回频率的字符串别名
print("\nString alias of the frequency from the 1st Period object ...\n", res1)
print("\nString alias of 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 String alias of the frequency from the 1st Period object ... <Second> String alias of the frequency from the 2nd Period object ... <YearEnd: month=12>
