Python Pandas - 检查 CustomBusinessDay Offset 是否已规范化

要检查 CustomBusinessDay Offset 是否已标准化，请使用CustomBusinessDay.normalizePandas 中的属性。

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('2021-10-22 03:10:35')

创建 CustomBusinessDay 偏移量。CustomBusinessDay 是 DateOffset 子类，表示不包括假期的自定义工作日。有效工作日的周掩码。我们使用“normalize”参数标准化了 CustomBusinessDay -

cbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 2, weekmask = 'Mon Tue Wed Fri', normalize=True)

将偏移量添加到时间戳并显示更新的时间戳 -

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

检查 CustomBusinessDay Offset 是否标准化 -

print("\nThe CustomBusinessDay Offset is normalized ?\n", cbdOffset.normalize)

示例

以下是代码 -

import pandas as pd

# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-10-22 03:10:35')

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

# Create the CustomBusinessDay Offset
# CustomBusinessDay is the DateOffset subclass representing custom business days excluding holidays
# Weekmask of valid business days
# We have normalized the CustomBusinessDay using the "normalize" parameter
cbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 2, weekmask = 'Mon Tue Wed Fri', normalize=True)

# Display the CustomBusinessDay Offset
print("\nCustomBusinessDay Offset...\n",cbdOffset)

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

# Return frequency applied on the given CustomBusinessDay Offset object as a string
print("\nFrequency applied on the given CustomBusinessDay Offset object...\n",cbdOffset.freqstr)

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

这将产生以下代码 -

Timestamp...
 2021-10-22 03:10:35

CustomBusinessDay Offset...
 <2 * CustomBusinessDays>

Updated Timestamp...
 2021-10-26 00:00:00

Frequency applied on the given CustomBusinessDay Offset object...
 2C

The CustomBusinessDay Offset is normalized ?
 True
