Python Pandas - 返回 Period 对象的时间戳表示形式
要返回 Period 对象的时间戳表示形式,请使用 period.to_timestamp() 方法。
首先,导入所需的库 −
import pandas as pd
pandas.Period 表示一段时间。创建一个 Period 对象
period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 17, minute = 20, second = 45)
显示 Period 对象
print("Period...\n", period)
返回 Period 对象的时间戳表示形式。我们使用 “freq” 参数设置了频率
print("\nPeriod to Timestamp...\n", period.to_timestamp(freq='T'))
示例
以下为代码
import pandas as pd # The pandas.Period represents a period of time # Creating a Period object period = pd.Period(freq="S", year = 2021, month = 9, day = 18, hour = 17, minute = 20, second = 45) # display the Period object print("Period...\n", period) # Return the Timestamp representation of the Period object # We have set the frequency using the "freq" parameter print("\nPeriod to Timestamp...\n", period.to_timestamp(freq='T'))
输出
这会生成以下代码
Period... 2021-09-18 17:20:45 Period to Timestamp... 2021-09-18 17:20:00
