Как скопировать файл на Python с индикатором выполнения?

Две вещи:

• Я бы сделал размер блока по умолчанию много больше 512. Я бы начал с 16384 и, возможно, больше.
• Для модульности было бы лучше, чтобы функция copy_with_prog не выводила саму полосу выполнения, а вызывала функцию обратного вызова, чтобы вызывающий мог решить, как отображать прогресс.

Возможно что-то вроде этого:

def copy_with_prog(src, dest, callback = None):
    while True:
        # copy loop stuff
        if callback:
            callback(pos, total)

prog = ProgressBar(...)
copy_with_prog(src, dest, lambda pos, total: prog.update(pos, total))

Перебор? Возможно. Но практически в любой системе, Linux, Mac, и с быстрой установкой wxWidgets в Windows вы можете получить реальную сделку с помощью кнопок паузы и отмены в настройке графического интерфейса. В наши дни Mac поставляются с wxWidgets, и это обычный пакет для Linux.

Один файл выполняется очень быстро (он сразу же завершится и будет выглядеть сломанным), поэтому вы можете подумать о создании задания fileSet, которое выполняется один раз для каждого файла, а не один раз для каждого блока. Наслаждаться!

Если вы хотите использовать диалоговое окно копирования Windows в процессе выполнения, вы можете использовать следующее:

• https://github.com/tjguk/winshell/
• https://github.com/frmdstryr/pywinutils

У меня есть shutil.copy () с индикатором выполнения, сделанным простым способом с помощью встроенных модулей. Если вы используете кодировку utf-8, вы можете добиться прогресса, как во втором примере на изображении в формате gif: Примеры индикаторов выполнения для этого:

Прочтите комментарии, чтобы изменить стиль и цвета. Первый и последний примеры не нуждаются в utf-8. Вы можете использовать команду CPprogress (SOURCE, DESTINATION) там, где у вас был shutil.copy (src, dst):

#!/usr/bin/env python
# -*- coding: utf-8 -*-
'''
CPprogress(SOURCE, DESTINATION)

I made this to give shutil.copy() [or shutil.copy2() in this case] a progress bar.

You can use CPprogress(SOURCE, DESTINATION) just like shutil.copy(src, dst). SOURCE must be a file path and DESTINATION a file or folder path.

It will give you a progress bar for each file copied. Just copy this code above the place where you want to use CPprogress(SOURCE, DESTINATION) in your code.

You can easily change the look of the progress bar:
    - To keep the style and just change the colors, replace the colors values of progressCOLOR and finalCOLOR (orange code at the end of the lines).
    - The use a solid block progress bar, # -*- coding: utf-8 -*- is required. Otherwise, you will get an encoding error. Some basic terminals, like xterm, may not show the progress bar because of the utf-8 characters.
      To use this style, remove the comments #STYLE# in lines ###COLORS### - BlueCOLOR and endBLOCK.
      In def getPERCECENTprogress() remove the comments  #STYLE# AND COMMENT THE PREVIOUS line. Do the same in def CPprogress()
      If you don't want the utf-8 encoding, delete the four lines beginning with #STYLE#.

NOTE: If you want to copy lots of small files, the copy process for file is so fast 
      that all you will see is a lot of lines scrolling in you terminal window - not enough time for a 'progress'.
      In that case, I use an overall progress that shows only one progress bar to the complete job.   nzX

Если вам нужен общий прогресс, вы можете использовать что-то вроде этого (сделано для другого скрипта).

CopyProgress('/path/to/SOURCE', '/path/to/DESTINATION')


I think this 'copy with overall progress' is very 'plastic' and can be easily adapted.
By default, it will RECURSIVELY copy the CONTENT of  'path/to/SOURCE' to 'path/to/DESTINATION/' keeping the directory tree.

Paying attention to comments, there are 4 main options that can be immediately change:

1 - The LOOK of the progress bar: see COLORS and the PAIR of STYLE lines in 'def getPERCECENTprogress'(inside and after the 'while' loop);

2 - The DESTINATION path: to get 'path/to/DESTINATION/SOURCE_NAME' as target, comment the 2nd 'DST =' definition on the top of the 'def CopyProgress(SOURCE, DESTINATION)' function;

3 - If you don't want to RECURSIVELY copy from sub-directories but just the files in the root source directory to the root of destination, you can use os.listdir() instead of os.walk(). Read the comments inside 'def CopyProgress(SOURCE, DESTINATION)' function to disable RECURSION. Be aware that the RECURSION changes(4x2) must be made in both os.walk() loops;

4 - Handling destination files: if you use this in a situation where the destination filename may already exist, by default, the file is skipped and the loop will jump to the next and so on. On the other way shutil.copy2(), by default, overwrites destination file if exists. Alternatively, you can handle files that exist by overwriting or renaming (according to current date and time). To do that read the comments after 'if os.path.exists(dstFILE): continue' both in the count bytes loop and the main loop. Be aware that the changes must match in both loops (as described in comments) or the progress function will not work properly.

В качестве альтернативы вы можете использовать ROBOCOPY с модулем os. Он не покажет вам индикатор выполнения, но он даст вам процентный индикатор, а также надежную сводку в конце.

import os

def robocopy(source, destination, extension=''):
    os.system("robocopy {} {} {} /xx /njh".format(source, destination, extension))

# Usage example
robocopy(r'C:\Users\Example\Downloads', r'C:\Users\Example\Desktop', '*.mov')

В приведенном выше примере все файлы .mov будут скопированы на рабочий стол.

Если оставить extension пустым, все файлы из исходной папки будут скопированы в папку назначения.

/xx удаляет лишние файлы / каталоги из списка

/njh удаляет заголовок задания
