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
