Python Pandas - 返回給定 BusinessHour 偏移物件上應用的頻率名稱


要返回給定 BusinessHour 偏移物件上應用的頻率名稱,請在 Pandas 中使用 BusinessHour.name 屬性。

首先,匯入所需的庫:

import pandas as pd

在 Pandas 中設定時間戳物件:

timestamp = pd.Timestamp('2021-1-1 01:55:30')

建立 BusinessHour 偏移量。BusinessHour 是 DateOffset 的子類:

bhOffset = pd.tseries.offsets.BusinessHour(start="09:30", end = "18:00")

顯示更新後的時間戳:

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

返回給定 BusinessHour 物件上應用的頻率名稱:

print("\nThe name of the frequency on the BusinessHour object..\n", bhOffset.name)

示例

以下是程式碼:

import pandas as pd

# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-1-1 01:55:30')

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

# Create the BusinessHour Offset
# BusinessHour is the DateOffset subclass
# 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")

# Display the BusinessHour Offset
print("\nBusinessHour Offset...\n",bhOffset)

# Display the Updated Timestamp
print("\nUpdated Timestamp...\n",timestamp + bhOffset)

# return the name of the frequency applied on the given BusinessHour object
print("\nThe name of the frequency on the BusinessHour object..\n", bhOffset.name)

輸出

這將產生以下程式碼:

Timestamp...
 2021-01-01 01:55:30

BusinessHour Offset...
 <BusinessHour: BH=09:30-18:00>

Updated Timestamp...
 2021-01-01 10:30:00

The name of the frequency on the BusinessHour object..
 BH
