Если файлы маленькие, вместо перемещения файлов вы можете просто:
- прочитать информацию из всех файлов
- найти данные, которые вы хотите заменить
- записать файлы с новыми данными в исходный каталог
- удалить старые файлы
Что-то вроде
def move_file(file_path, dst_path):
with open(file_path, "r") as input_file, open(dst_path, "w") as output_file:
for line in input_file:
if <line meets criteria to modify>:
<modify_line>
print(line, file=output_file)
for <data> in <additional_data>:
print(<data>, file=output_file)
# remove the old file
os.remove(file_path)
Тогда вместо os. переименуйте в исходном коде вызовите функцию move_file
#Now we are selecting the files which will be moved
#and make a destination path for them.
for file_path in all_file_paths:
if file_path == newest_file_paths and os.path.getctime(newest_file_paths) < time.time() - 120:
dst_root = destination
else:
dst_root = archive
#Now its time to make the move.
dst_path = os.path.join(dst_root, subdir, os.path.basename(file_path))
move_file(file_path, dst_path)
Вы можете реализовать это как
import os
import time
from datetime import datetime
SOURCE = r'c:\data\AS\Desktop\Source'
DESTINATION = r'c:\data\AS\Desktop\Destination'
ARCHIVE = r'c:\data\AS\Desktop\Archive'

minutes = (time_difference.total_seconds() % 3600) // 60
return f"{int(hours)}:{int(minutes)}"
