Python Pandas - 检查 BusinessHour 偏移量是否已标准化


如需检查 BusinessHour 偏移量是否已标准化,请在 Pandas 中使用 BusinessHour.normalize 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('2021-1-1 01:55:30')

创建 BusinessHour 偏移量。我们使用“normalize”参数标准化了 BusinessHour −

bhOffset = pd.tseries.offsets.BusinessHour(start="09:30", end = "18:00", normalize=True)

显示更新的时间戳 −

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

检查 BusinessHour 偏移量是否已标准化 −

print("\nThe BusinessHour Offset is normalized ?\n", bhOffset.normalize)

示例

以下是代码 −

import pandas as pd

# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-1-1 01:55:30')

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

# Create the BusinessHour Offset
# BusinessHour 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.
# We have normalized the BusinessHour using the "normalize" parameter
bhOffset = pd.tseries.offsets.BusinessHour(start="09:30", end = "18:00", normalize=True)

# Display the BusinessHour Offset
print("\nBusinessHour Offset...\n",bhOffset)

# Display the Updated Timestamp
print("\nUpdated Timestamp...\n",timestamp + bhOffset)

# check whether the BusinessHour Offset is normalized or not
print("\nThe BusinessHour Offset is normalized ?\n", bhOffset.normalize)

输出

这会产生以下代码 −

Timestamp...
 2021-01-01 01:55:30

BusinessHour Offset...
 <BusinessHour: BH=09:30-18:00>

Updated Timestamp...
 2021-01-01 00:00:00

The BusinessHour Offset is normalized ?
 True
