法学Python Pandas - 获取给定 CustomBusinessHour 偏移量对象的频率名称
要返回给定 CustomBusinessHour 偏移量对象上应用的频率的名称，请在 Pandas 中使用 CustomBusinessHour.name 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('2021-10-25 08:35:10')
创建 CustomBusinessHour 偏移量。CustomBusinessHour 是 DateOffset 的子类：
cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 3, weekmask = 'Mon Tue Wed Fri Sat')
将偏移量添加到时间戳并显示更新后的时间戳：
print("\nUpdated Timestamp...\n",timestamp + cbhOffset)
返回给定 CustomBusinessHour 对象上应用的频率的名称：
print("\nThe name of the frequency on the CustomBusinessHour object..\n", cbhOffset.name)示例
以下是代码：
import pandas as pd
# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-10-25 08:35:10')
# Display the Timestamp
print("Timestamp...\n",timestamp)
# Create the CustomBusinessHour Offset
# CustomBusinessHour is the DateOffset subclass
# Weekmask of valid business days
cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 3, weekmask = 'Mon Tue Wed Fri Sat')
# Display the CustomBusinessHour Offset
print("\nCustomBusinessHour Offset...\n",cbhOffset)
# Add the offset to the Timestamp and display the Updated Timestamp
print("\nUpdated Timestamp...\n",timestamp + cbhOffset)
# Return frequency applied on the given CustomBusinessHour Offset object as a string
print("\nFrequency applied on the given CustomBusinessHour Offset object...\n",cbhOffset.freqstr)
# return the name of the frequency applied on the given CustomBusinessHour object
print("\nThe name of the frequency on the CustomBusinessHour object..\n", cbhOffset.name)输出
这将产生以下代码：
Timestamp... 2021-10-25 08:35:10 CustomBusinessHour Offset... <3 * CustomBusinessHours: CBH=09:00-17:00> Updated Timestamp... 2021-10-25 12:00:00 Frequency applied on the given CustomBusinessHour Offset object... 3CBH The name of the frequency on the CustomBusinessHour object.. CBH
