Python Pandas CustomBusinessHour - 仅当不在偏移量上时，将提供日期向前滚动到下一个偏移量

若要仅在未使用偏移量时将提供日期向前滚动到下一个偏移量，请使用 Pand 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 偏移。CustomBusinessHour 是 DateOffset 子类。合法工作日的星期掩码 −

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

将偏移量添加到时间戳并显示更新后的时间戳 −

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

若未使用偏移量，则向前滚动 −

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

显示结果 −

print("\nRoll forward Result...\n",roll)

示例

以下是代码 −

import pandas as pd

# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-12-20 08:35:10')

# Display the Timestamp
print("Timestamp...\n",timestamp)

# Create the CustomBusinessHour Offset
# CustomBusinessHour is the DateOffset subclass
# Weekmask of valid business days
cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 5, weekmask = 'Mon Tue Wed Fri')

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

# Add the offset to the Timestamp and display the Updated Timestamp
print("\nUpdated Timestamp...\n",timestamp + cbhOffset)

# roll forward if not on offset
roll = cbhOffset.rollforward(pd.Timestamp('2021-12-30 08:35:10'))

# display the result
print("\nRoll forward Result...\n",roll)

输出

这将生成以下代码 −

Timestamp...
 2021-12-20 08:35:10

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

Updated Timestamp...
 2021-12-20 14:00:00

Roll forward Result...
 2021-12-31 09:00:00
