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
