Python Pandas - 获取应用于 CustomBusinessDay 偏移量的周掩码

要在CustomBusinessDay偏移量上应用周掩码，请使用CustomBusinessDay.weekmaskPandas中的属性。

首先，导入所需的库-

import pandas as pd

在Pandas中设置时间戳对象-

timestamp = pd.Timestamp(2021-10-22 03:10:35)

创建CustomBusinessDay偏移量。CustomBusinessDay是DateOffset子类，表示不包括假期的自定义工作日。有效工作日的周掩码-

cbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 4, weekmask = Mon Tue Wed Fri)

将偏移量添加到时间戳并显示更新的时间戳-

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

显示周掩码-

print("\nThe weekmask on the CustomBusinessDay object..\n", cbdOffset.weekmask)

示例

以下是代码-

import pandas as pd #SetthetimestampobjectinPandas timestamp = pd.Timestamp(2021-10-22 03:10:35) #DisplaytheTimestamp print("Timestamp...\n",timestamp) #CreatetheCustomBusinessDayOffset #CustomBusinessDayistheDateOffsetsubclassrepresentingcustombusinessdaysexcludingholidays #Weekmaskofvalidbusinessdays cbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 4, weekmask = Mon Tue Wed Fri) #DisplaytheCustomBusinessDayOffset print("\nCustomBusinessDay Offset...\n",cbdOffset) #AddtheoffsettotheTimestampanddisplaytheUpdatedTimestamp print("\nUpdated Timestamp...\n",timestamp + cbdOffset) #ReturnfrequencyappliedonthegivenCustomBusinessDayOffsetobjectasastring print("\nFrequency applied on the given CustomBusinessDay Offset object...\n",cbdOffset.freqstr) #returnthecountofincrementsonthegivenCustomBusinessDayobject print("\nThe count of increments on the CustomBusinessDay object..\n", cbdOffset.n) #displaytheweekmask print("\nThe weekmask on the CustomBusinessDay object..\n", cbdOffset.weekmask)输出结果

这将产生以下代码-

Timestamp... 2021-10-22 03:10:35 CustomBusinessDay Offset... <4 * CustomBusinessDays> Updated Timestamp... 2021-10-29 03:10:35 Frequency applied on the given CustomBusinessDay Offset object... 4C The count of increments on the CustomBusinessDay object.. 4 The weekmask on the CustomBusinessDay object.. Mon Tue Wed Fri
