Python Pandas - 以字符串形式应用于给定 CustomBusinessDay Offset 对象的返回频率

要将应用于给定 CustomBusinessDay Offset 对象的频率作为字符串返回，请使用该CustomBusinessDay.freqstr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 -

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的时间戳 -

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

以字符串形式应用于给定 CustomBusinessDay Offset 对象的返回频率 -

print("\nFrequency applied on the given CustomBusinessDay Offset object...\n",cbdOffset.freqstr)

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)

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...
