Python Pandas - 查找给定 Period 对象的开始时间
要查找给定Period对象的开始时间，请使用period.start_time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("2020-09-22")
period2 = pd.Period(freq="D", year = 2021, month = 2, day = 14, hour = 2, minute = 35)显示期间对象
print("Period1...\n", period1)
print("Period2...\n", period2)从两个Period对象获取开始时间
res1 = period1.start_time res2 = period2.start_time
示例
以下是代码
import pandas as pd
#Thepandas.Period代表一段时间
#创建两个Period对象
period1 = pd.Period("2020-09-22")
period2 = pd.Period(freq="D", 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对象获取开始时间
res1 = period1.start_time
res2 = period2.start_time
#从两个Period对象返回开始时间
print("\nDisplay the start time from the 1st Period object ...\n", res1)
print("\nDisplay the start time from the 2nd Period object ...\n", res2)输出结果这将产生以下代码
Period1... 2020-09-22 Period2... 2021-02-14 Display the start time from the 1st Period object ... 2020-09-22 00:00:00 Display the start time from the 2nd Period object ... 2021-02-14 00:00:00
