Python Pandas – 将Period对象作为带有年度频率的时间戳返回

要将Period对象作为带有年度频率的时间戳返回，请使用period.to_timestamp()方法，并将freq参数设置为‘Y’。

首先，导入所需的库 –

import pandas as pd

pandas.Period表示一段时间。创建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。我们使用“freq”参数设置频率。将频率设置为’Y’，即每年一次。

print("\nPeriod to Timestamp with yearly (year-end) frequency...\n", period.to_timestamp(freq = 'Y'))

示例

下面是代码 –

import pandas as pd

# pandas.Period表示一段时间
# 创建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)

# 将Period对象返回为时间戳
# 我们使用“freq”参数设置频率
# 频率设置为'Y'，即每年一次
print("\nPeriod to Timestamp with yearly (year-end) frequency...\n", period.to_timestamp(freq = 'Y'))

输出

这将产生以下代码 –

Period...
2021-09-18 17:20:45

Period to Timestamp with yearly (year-end) frequency...
