要将应用于给定 BusinessHour Offset 对象的频率作为字符串返回,请使用BusinessHour.freqstrPandas 中的属性。
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('2021-1-1 01:55:30')
创建营业时间偏移量 -
bhOffset = pd.tseries.offsets.BusinessHour(start="09:30", end = "18:00")
显示更新的时间戳 -
print("\nUpdated Timestamp...\n",timestamp + bhOffset)
以字符串形式应用于给定 BusinessHour Offset 对象的返回频率 -
print("\nFrequency applied on the given BusinessHour Offset object...\n",bhOffset.freqstr)
以下是代码 -
import pandas as pd # 在 Pandas 中设置时间戳对象 timestamp = pd.Timestamp('2021-1-1 01:55:30') # 显示时间戳 print("Timestamp...\n",timestamp) # 创建营业时间偏移 # BusinessHour 是 DateOffset 子类 # Here, "start" is the start time of your custom business hour in 24h format. # The "end" is the end time of your custom business hour in 24h format. bhOffset = pd.tseries.offsets.BusinessHour(start="09:30", end = "18:00") # 显示营业时间偏移 print("\nBusinessHour Offset...\n",bhOffset) # 显示更新的时间戳 print("\nUpdated Timestamp...\n",timestamp + bhOffset) # 以字符串形式应用于给定 BusinessHour Offset 对象的返回频率 print("\nFrequency applied on the given BusinessHour Offset object...\n",bhOffset.freqstr)输出结果
这将产生以下代码 -
Timestamp... 2021-01-01 01:55:30 BusinessHour Offset... <BusinessHour: BH=09:30-18:00> Updated Timestamp... 2021-01-01 10:30:00 Frequency applied on the given BusinessHour Offset object... BH
