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
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
的pandas.Period代表的一段时间。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
#Thepandas.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)输出结果这将产生以下代码-
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>
