Python Pandas – 获取应用于CustomBusinessHour偏移量的weekmask

要获取应用于CustomBusinessHour偏移量的weekmask，请在Pandas中使用CustomBusinessHour.weekmask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('2021-11-14 05:20:30')

创建CustomBusinessHour Offset。CustomBusinessHour是DateOffset子类。有效工作日的weekmask-

cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 7, weekmask = 'Mon Tue Wed Fri')

将Offset添加到Timestamp中并显示更新的Timestamp-

print("\n更新后的Timestamp...\n",timestamp + cbhOffset)

显示weekmask-

print("\nCustomBusinessHour对象的weekmask..\n", cbhOffset.weekmask)

示例

以下是代码-

import pandas as pd

# 在Pandas中设置时间戳对象
timestamp = pd.Timestamp('2021-11-14 05:20:30')

# 显示Timestamp
print("Timestamp...\n",timestamp)

# 创建CustomBusinessHour Offset
# CustomBusinessHour是DateOffset子类
# 有效工作日的weekmask
cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 7, weekmask = 'Mon Tue Wed Fri')

# 显示CustomBusinessHour Offset
print("\nCustomBusinessHour Offset...\n",cbhOffset)

# 将Offset添加到Timestamp中并显示更新的Timestamp
print("\n更新后的Timestamp...\n",timestamp + cbhOffset)

# 将给定的CustomBusinessHour Offset对象应用的频率作为字符串返回
print("\n应用在给定CustomBusinessHour Offset对象上的频率...\n",cbhOffset.freqstr)

# 显示weekmask
print("\nCustomBusinessHour对象的weekmask..\n", cbhOffset.weekmask)

输出

这将产生以下代码-

Timestamp...
2021-11-14 05:20:30

CustomBusinessHour Offset...
<7 * CustomBusinessHours: CBH=09:00-17:00>

更新后的Timestamp...
2021-11-15 16:00:00

应用在给定CustomBusinessHour Offset对象上的频率...
7CBH

CustomBusinessHour对象的weekmask..
Mon Tue Wed Fri
