def arrange_by_date():
    df = pd.read_excel("logfile_Final_test.xlsx")
    df = df.sort_values(by="Date", ascending=True).set_index('Date').last('3M')
    df = df.sort_values(by="Date", ascending=False)
    df.to_excel("Master_logfile.xlsx", index=True)


arrange_by_date()

excel表格中的數據為

  Database         Date       Time         Description
Some_DB_name    2022-12-25   some_time    Some_Description
Some_DB_name    2023-01-14   some_time    Some_Description

正如@roganjosh 所指出的，它應該沒有任何區別，但如果你必須只有日期並刪除時間元素，因為你的 'date 列是 df 索引，你可以使用：

df['Date'] = df['Date'].date
