Python Pandas CustomBusinessHour – 只有不在偏移处时才将提供的日期向前滚动到下一个偏移

要只有在不在偏移位置时才将提供的日期向前滚动到下一个偏移，请使用Pandas中的CustomBusinessHour.rollforward()方法。

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('2021-12-20 08:35:10')

创建CustomBusinessHour Offset。 CustomBusinessHour是DateOffset子类。有效工作日的周掩码−

cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 5, weekmask = 'Mon Tue Wed Fri')

将偏移添加到时间戳并显示更新的时间戳−

print("\n更新时间戳...\n",timestamp + cbhOffset)

如果不处于偏移处，请向前滚动−

roll = cbhOffset.rollforward(pd.Timestamp('2021-12-30 08:35:10'))

显示结果 −

print("\n向前滚动结果...\n",roll)

示例

以下是代码−

import pandas as pd

# 在Pandas中设置时间戳对象
timestamp = pd.Timestamp('2021-12-20 08:35:10')

# 显示时间戳
print("时间戳...\n",timestamp)

# 创建CustomBusinessHour Offset
# CustomBusinessHour是DateOffset子类
# 有效工作日的周掩码
cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 5, weekmask = 'Mon Tue Wed Fri')

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

# 将偏移添加到时间戳并显示更新的时间戳
print("\n更新时间戳...\n",timestamp + cbhOffset)

# 如果不在偏移处，则向前滚动
roll = cbhOffset.rollforward(pd.Timestamp('2021-12-30 08:35:10'))

# 显示结果
print("\n向前滚动结果...\n",roll)

输出

这将产生以下代码−

时间戳...
2021-12-20 08:35:10

CustomBusinessHour Offset...
<5 * CustomBusinessHours: CBH=09:00-17:00>

更新时间戳...
2021-12-20 14:00:00

向前滚动结果...
2021-12-31 09:00:00
