Python Pandas - 將給定的BusinessDay Offset物件頻率作為字串返回
要將給定的BusinessDay Offset物件的應用頻率作為字串返回,請在Pandas中使用BusinessDay.freqstr屬性。
首先,匯入所需的庫:
import datetime import pandas as pd
在Pandas中設定時間戳物件:
timestamp = pd.Timestamp('2021-1-1 01:55:02.000045')
建立BusinessDay Offset。BusinessDay是DateOffset的子類:
bdOffset = pd.tseries.offsets.BusinessDay(offset = datetime.timedelta(days = 7, hours = 7, minutes = 7))
顯示更新後的時間戳:
print("\nUpdated Timestamp...\n",timestamp + bdOffset)
將應用於給定BusinessDay物件的頻率作為字串返回:
print("\nFrequency on the given BusinessDay Offset...\n",bdOffset.freqstr)
示例
以下是程式碼:
import datetime import pandas as pd # Set the timestamp object in Pandas timestamp = pd.Timestamp('2021-1-1 01:55:02.000045') # Display the Timestamp print("Timestamp...\n",timestamp) # Create the BusinessDay Offset # BusinessDay is the DateOffset subclass bdOffset = pd.tseries.offsets.BusinessDay(offset = datetime.timedelta(days = 7, hours = 7, minutes = 7)) # Display the BusinessDay Offset print("BusinessDay Offset...\n",bdOffset) # Display the Updated Timestamp print("\nUpdated Timestamp...\n",timestamp + bdOffset) # return the frequency applied on the given BusinessDay object as a string print("\nFrequency on the given BusinessDay Offset...\n",bdOffset.freqstr)
輸出
這將產生以下程式碼:
Timestamp... 2021-01-01 01:55:02.000045 BusinessDay Offset... <BusinessDay: offset=datetime.timedelta(days=7, seconds=25620)> Updated Timestamp... 2021-01-11 09:02:02.000045 Frequency on the given BusinessDay Offset... B+7D7H7Min
