Python Pandas - 获取给定 CustomBusinessHour 对象上应用的规则代码

要返回给定 CustomBusinessHour 对象上应用的规则代码，请在 Pandas 中使用 CustomBusinessHour.rule_code 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('2021-11-14 05:20:30')

创建 CustomBusinessHour 偏移量。CustomBusinessHour 是 DateOffset 的子类：

cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 4, weekmask = 'Mon Tue Wed Fri Sat' ,normalize=True)

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)

返回应用于给定 CustomBusinessHour 偏移量的频率的规则代码：

print("\nThe rule code of the CustomBusinessHour object..\n", cbhOffset.rule_code)

示例

以下是代码：

import pandas as pd

# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-11-14 05:20:30')

# Display the Timestamp
print("Timestamp...\n",timestamp)

# Create the CustomBusinessHour Offset
# CustomBusinessHour is the DateOffset subclass
# Weekmask of valid business days
# We have normalized the CustomBusinessDay using the "normalize" parameter
cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 4, weekmask = 'Mon Tue Wed Fri Sat' ,normalize=True)

# 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 rule code of the frequency applied on the given CustomBusinessHour Offset
print("\nThe rule code of the CustomBusinessHour object..\n", cbhOffset.rule_code)

输出

这将产生以下代码：

Timestamp...
2021-11-14 05:20:30

CustomBusinessHour Offset...
<4 * CustomBusinessHours: CBH=09:00-17:00>

Updated Timestamp...
2021-11-15 00:00:00

Frequency applied on the given CustomBusinessHour Offset object...
4CBH

The rule code of the CustomBusinessHour object..
CBH
