Python Pandas - 檢查給定的 DateOffset 是否已錨定
要檢查給定的 DateOffset 是否已錨定,請在 Pandas 中使用 offset.is_anchored() 方法。首先,匯入所需的庫 −
from pandas.tseries.frequencies import to_offset import pandas as pd
在 Pandas 中設定時間戳物件 −
timestamp = pd.Timestamp('2021-09-26 03:25:02.000045')
建立 DateOffset。在這裡,我們使用錨定偏移,即星期頻率,具體為星期二 −
offset = to_offset("W-TUE")顯示更新的時間戳 −
print("\nUpdated Timestamp...\n",timestamp + offset)
檢查 DateOffset 是否已錨定 −
print("\nCheck whether the DateOffset is anchored...\n", offset.is_anchored())示例
以下是程式碼 −
from pandas.tseries.frequencies import to_offset
import pandas as pd
# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-09-26 03:25:02.000045')
# Display the Timestamp
print("Timestamp...\n",timestamp)
# Create the DateOffset
# We are using the Anchored offset i.e. weekly frequency here for Tuesday
offset = to_offset("W-TUE")
# Display the DateOffset
print("\nDateOffset...\n",offset)
# Display the Updated Timestamp
print("\nUpdated Timestamp...\n",timestamp + offset)
# Check whether the DateOffset is anchored
print("\nCheck whether the DateOffset is anchored...\n", offset.is_anchored())輸出
這將生成以下程式碼 −
Timestamp... 2021-09-26 03:25:02.000045 DateOffset... <Week: weekday=1> Updated Timestamp... 2021-09-28 03:25:02.000045 Check whether the DateOffset is anchored... True
