Python Pandas – 返回给定CustomBusinessDay Offset对象应用的频率，表示为字符串

要返回给定CustomBusinessDay Offset对象应用的频率并表示为字符串，请使用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 Offset—

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("\n更新后的时间戳...\n",timestamp + cbdOffset)

返回给定CustomBusinessDay Offset对象应用的频率并用字符串表示—

print("\n给定CustomBusinessDay Offset对象应用的频率...\n",cbdOffset.freqstr)

示例

以下是代码—

import pandas as pd

# 在pandas中设置时间戳对象
timestamp = pd.Timestamp('2021-12-31 08:35:10')

# 显示时间戳
print("时间戳...\n",timestamp)

# 创建CustomBusinessDay Offset
# CustomBusinessDay是DateOffset子类，表示不包括节假日的自定义工作日
# 有效工作日的周掩码
cbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 2, weekmask = 'Mon Tue Wed Fri')

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

# 将偏移量添加到时间戳并显示更新的时间戳
print("\n更新后的时间戳...\n",timestamp + cbdOffset)

# 返回给定CustomBusinessDay Offset对象应用的频率并用字符串表示
print("\n给定CustomBusinessDay Offset对象应用的频率...\n",cbdOffset.freqstr)

输出

这将产生以下代码—

时间戳...
 2021-12-31 08:35:10

CustomBusinessDay Offset...
 <2 * CustomBusinessDays>

更新后的时间戳...
 2022-01-04 08:35:10

给定CustomBusinessDay Offset对象应用的频率...
