Python Pandas - 返回给定 DateOffset 对象中的纳秒数

要返回给定DateOffset对象中的纳秒数，请使用offset.nanosPandas中的属性。

首先，导入所需的库-

from pandas.tseries.frequencies import to_offset import pandas as pd

在Pandas中设置时间戳对象-

timestamp = pd.Timestamp(2021-08-30 03:08:02.000045)

创建日期偏移量。我们在这里使用“D”频率增加天数-

offset = to_offset("5D")

显示更新的时间戳-

print("\nUpdated Timestamp...\n",timestamp + offset)

返回给定DateOffset对象中的纳秒-

print("\nThe number of nanoseconds in the DateOffset object..\n", offset.nanos)

示例

以下是代码-

from pandas.tseries.frequencies import to_offset import pandas as pd #在Pandas中设置时间戳对象 timestamp = pd.Timestamp(2021-08-30 03:08:02.000045) #显示时间戳 print("Timestamp...\n",timestamp) #创建日期偏移 # We are incrementing the days here using the "D" frequency offset = to_offset("5D") #显示日期偏移 print("\nDateOffset...\n",offset) #显示更新的时间戳 print("\nUpdated Timestamp...\n",timestamp + offset) #返回给定DateOffset对象中的纳秒 print("\nThe number of nanoseconds in the DateOffset object..\n", offset.nanos)输出结果

这将产生以下代码-

Timestamp... 2021-08-30 03:08:02.000045 DateOffset... <5 * Days> Updated Timestamp... 2021-09-04 03:08:02.000045 The number of nanoseconds in the DateOffset object.. 432000000000000
