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

要将应用于给定BusinessDayOffset对象的频率作为字符串返回，请使用BusinessDay.freqstrPandas中的属性。

首先，导入所需的库-

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)

创建工作日偏移量。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("\nUpdated Timestamp...\n",timestamp + bdOffset)

以字符串形式返回应用于给定BusinessDay对象的频率-

print("\nFrequency on the given BusinessDay Offset...\n",bdOffset.freqstr)

示例

以下是代码-

import datetime import pandas as pd #SetthetimestampobjectinPandas timestamp = pd.Timestamp(2021-1-1 01:55:02.000045) #DisplaytheTimestamp print("Timestamp...\n",timestamp) #CreatetheBusinessDayOffset #BusinessDayistheDateOffsetsubclass bdOffset = pd.tseries.offsets.BusinessDay(offset = datetime.timedelta(days = 7, hours = 7, minutes = 7)) #DisplaytheBusinessDayOffset print("BusinessDay Offset...\n",bdOffset) #DisplaytheUpdatedTimestamp print("\nUpdated Timestamp...\n",timestamp + bdOffset) #returnthefrequencyappliedonthegivenBusinessDayobjectasastring print("\nFrequency on the given BusinessDay Offset...\n",bdOffset.freqstr)输出结果

这将产生以下代码-

Timestamp... 2021-01-01 01:55:02.000045 BusinessDay Offset... <BusinessDay: offset=datetime.timedelta(days=7, seconds=25620)> Updated Timestamp... 2021-01-11 09:02:02.000045 Frequency on the given BusinessDay Offset... B+7D7H7Min
