如何創建/填充ods文件中的工作表而不破壞文件中的其他工作表？

Question

我的Python代碼用於從.csv文件獲取數據並轉換並將其保存到.ods文件。問題是，當它保存到新文件時，它將刪除保存的文件中的其他工作表。如何在不刪除其他工作表的情況下更新新文件？

import csv, shutil, os, glob 
from pyexcel_ods3 import save_data 
from collections import OrderedDict 

# finds the latest file from my downloads folder 
newest = max(glob.iglob('*.csv'), key=os.path.getctime) 

my_file = open(newest) 
file_reader = csv.reader(my_file) 
file_data = list(file_reader) 

# identifies the data structure 
file_header = ['Details', 'Posting Date', 'Description', 'Amount', 'Type', 'Balance', 'Check or Slip #'] 

# compares the data structure in the csv file to the one used for this script 
if file_data[0] == file_header: 
    del file_data[0] # removes the header form the csv file 
    date = file_data[0][1] 
    f_date = date.split('/') 
    f_date_formatted = '{}-{}-{}'.format(f_date[2], f_date[0], f_date[1]) 
    for i in file_data: # organizes the data 
     i[4] = '' 
     transaction = float(i[3]) 
     if transaction > 0: 
      i[3] = '' 
      i[4] = transaction 
    my_file.close() 

    # creates a copy of the unpopulated file. This file has 3 existing sheets. One sheet is called 'DATA' 
    shutil.copy('Checkbook Monthly balance.ods', 'Checkbook Monthly balance thru {}.ods'.format(f_date_formatted)) 

    # populates the sheet called 'DATA' 
    data = OrderedDict() 
    data.update({'DATA': file_data}) 
    save_data('Checkbook Monthly balance thru {}.ods'.format(f_date_formatted), data) 

else: 
    print('It appears the bank changed the table format. Check the .csv file for a difference in the data structure.') 
    my_file.close()

由於舊文件已超過寫的，以前的數據被殲滅。

爲了保留現有數據，您需要通過'get_data(..)'讀取數據，然後附加內容並將其全部保存。
