Python Pandas – 将给定的BusinessDay偏移对象的频率作为字符串返回

要将给定的BusinessDay偏移对象的频率作为字符串返回，请使用Pandas中的BusinessDay.freqstr属性。

首先，导入所需的库-

import datetime
import pandas as pd

设置Pandas中的时间戳对象-

timestamp = pd.Timestamp('2021-1-1 01:55:02.000045')

创建BusinessDay Offset。BusinessDay是DateOffset子类-

bdOffset = pd.tseries.offsets.BusinessDay(offset = datetime.timedelta(days = 7, hours = 7, minutes = 7))

显示更新的时间戳-

print("\n更新时间戳...\n",timestamp + bdOffset)

将给定的BusinessDay对象应用的频率作为字符串返回-

print("\n给定BusinessDay Offset的频率...\n",bdOffset.freqstr)

例子

以下是代码-

import datetime
import pandas as pd

# 在Pandas中设置时间戳对象
timestamp = pd.Timestamp('2021-1-1 01:55:02.000045')

# 显示时间戳
print("时间戳...\n",timestamp)

# 创建BusinessDay Offset
# BusinessDay是DateOffset子类
bdOffset = pd.tseries.offsets.BusinessDay(offset = datetime.timedelta(days = 7, hours = 7, minutes = 7))

# 显示BusinessDay Offset
print("BusinessDay Offset...\n",bdOffset)

# 显示更新的时间戳
print("\n更新时间戳...\n",timestamp + bdOffset)

# 将给定的BusinessDay对象应用的频率作为字符串返回
print("\n给定BusinessDay Offset的频率...\n",bdOffset.freqstr)

输出

这将产生以下代码-

时间戳...
 2021-01-01 01:55:02.000045
BusinessDay Offset...
 <BusinessDay: offset=datetime.timedelta(days=7, seconds=25620)>

更新时间戳...
 2021-01-11 09:02:02.000045

给定BusinessDay Offset的频率...
