Python Pandas - 从 CustomBusinessHour 偏移量对象中以 24 小时格式显示自定义营业时间的开始时间

要从 CustomBusinessHour 偏移量对象中以 24 小时格式显示自定义营业时间的开始时间，请在 Pandas 中使用 CustomBusinessHour.start 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 偏移量。这里，“start” 是您自定义营业时间以 24 小时格式表示的开始时间。“end” 是您自定义营业时间以 24 小时格式表示的结束时间 -

cbhOffset = pd.tseries.offsets.CustomBusinessHour(start="09:30", end = "18:00", n = 8)

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)

显示自定义营业时间的开始时间 -

print("\nThe start time of the custom business hour...\n",cbhOffset.start)

示例

以下是代码 -

import pandas as pd

# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-11-14 05:20:30')

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

# Create the CustomBusinessHour Offset
# CustomBusinessHour is the DateOffset subclass
# Here, "start" is the start time of your custom business hour in 24h format.
# The "end" is the end time of your custom business hour in 24h format.
cbhOffset = pd.tseries.offsets.CustomBusinessHour(start="09:30", end = "18:00", n = 8)

# 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)

# Display the start time of the custom business hour
print("\nThe start time of the custom business hour...\n",cbhOffset.start)

输出

这将生成以下代码 -

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

CustomBusinessHour Offset...
 <8 * CustomBusinessHours: CBH=09:30-18:00>

Updated Timestamp...
 2021-11-15 17:30:00

The start time of the custom business hour...
 (datetime.time(9, 30),)
