Python Pandas - 检查 CustomBusinessHour Offset 是否已标准化

要检查 CustomBusinessHour Offset 是否已规范化，请使用CustomBusinessHour.normalizePandas 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('2021-10-25 08:35:10')

创建 CustomBusinessHour 偏移量。CustomBusinessHour 是 DateOffset 子类。我们使用“normalize”参数标准化了 CustomBusinessDay -

cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 3, weekmask = 'Mon Tue Wed Fri Sat' ,normalize=True)

将偏移量添加到时间戳并显示更新的时间戳 -

print("\nUpdated Timestamp...\n",timestamp + cbhOffset)

检查 CustomBusinessHour Offset 是否标准化 -

print("\nThe CustomBusinessHour Offset is normalized ?\n", cbhOffset.normalize)

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
# We have normalized the CustomBusinessDay using the "normalize" parameter
cbhOffset = pd.tseries.offsets.CustomBusinessHour(n = 3, 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 name of the frequency applied on the given CustomBusinessHour object
print("\nThe name of the frequency on the CustomBusinessHour object..\n", cbhOffset.name)

# check whether the CustomBusinessHour Offset is normalized or not
print("\nThe CustomBusinessHour Offset is normalized ?\n", cbhOffset.normalize)

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 00:00:00

Frequency applied on the given CustomBusinessHour Offset object...
 3CBH

The name of the frequency on the CustomBusinessHour object..
 CBH

The CustomBusinessHour Offset is normalized ?
 True
