Python Pandas - 返回给定 CustomBusinessDay 偏移对象上应用的频率名称

要返回给定 CustomBusinessDay 偏移对象上应用的频率名称，请使用 CustomBusinessDay.name 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('2021-12-31 08:35:10')

创建 CustomBusinessDay 偏移量。CustomBusinessDay 是 DateOffset 子类，表示自定义工作日，不包括节假日 -

cbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 2, 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 + cbdOffset)

返回给定 CustomBusinessDay 对象上应用的频率名称 -

print("\nThe name of the frequency on the CustomBusinessDay object..\n", cbdOffset.name)

示例

以下是代码 -

import pandas as pd

# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-12-31 08:35:10')

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

# 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)

# return the name of the frequency applied on the given CustomBusinessDay object
print("\nThe name of the frequency on the CustomBusinessDay object..\n", cbdOffset.name)

输出

这将产生以下代码 -

Timestamp...
 2021-12-31 08:35:10

CustomBusinessDay Offset...
 <2 * CustomBusinessDays>

Updated Timestamp...
 2022-01-04 08:35:10

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

The name of the frequency on the CustomBusinessDay object..
 C
