Python Pandas - 返回應用於給定 DateOffset 物件的頻率
若要返回應用於給定 DateOffset 物件的頻率,請使用 Pandas 中的 offset.freqstr。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。這裡使用“D”頻率遞增天數 −
offset = to_offset("5D")顯示更新的時間戳 −
print("\nUpdated Timestamp...\n",timestamp + offset)
返回應用於給定 DateOffset 物件的頻率 −
print("\nThe frequency on the DateOffset object..\n", offset.freqstr)示例
程式碼如下 −
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 incrementing the days here using the "D" frequency
offset = to_offset("5D")
# Display the DateOffset
print("\nDateOffset...\n",offset)
# Display the Updated Timestamp
print("\nUpdated Timestamp...\n",timestamp + offset)
# return the frequency applied on the given DateOffset object
print("\nThe frequency on the DateOffset object..\n", offset.freqstr)輸出
這將產生以下程式碼 −
Timestamp... 2021-09-26 03:25:02.000045 DateOffset... <5 * Days> Updated Timestamp... 2021-10-01 03:25:02.000045 The frequency on the DateOffset object.. 5D
