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_timeres2 = period2.start_time
示例
以下是代码
import pandas as pd输出结果# 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)
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
