python - 将文件夹和文件替换为最新的

问题描述

我想将文件夹和文件从源目录复制到另一个目标目录。每个目录已经包含子文件夹和许多文件。
到目前为止，我尝试了以下代码，灵感来自 Stackoverflow 中的一篇文章：

import os
import shutil

root_src_dir = r'C:\....'
root_dst_dir  = r'C:\....'

for src_dir, dirs, files in os.walk(root_src_dir):
    dst_dir = src_dir.replace(root_src_dir, root_dst_dir, 1)
    if not os.path.exists(dst_dir):
        os.makedirs(dst_dir)
    for file_ in files:
        src_file = os.path.join(src_dir, file_)
        dst_file = os.path.join(dst_dir, file_)
        if os.path.exists(dst_file):
            # in case of the src and dst are the same file
            if os.path.samefile(src_file, dst_file):
                continue
            os.remove(dst_file)
        shutil.copy2(src_file, dst_dir)

对于相同的文件夹和文件名，此代码将目标目录与源目录等同起来。这可以替换目标中最新的文件夹和文件，这是一场灾难，而我想将最新的文件夹和文件保留在两个目录中，因为它们具有相同的文件夹和文件名。

解决方案

这是我写的一个程序。它是一种交互式的，还具有移动和删除功能以及复制。并根据扩展名过滤数据。

import os
import shutil
from os.path import join
from time import perf_counter
print('Written By : SaGaR')
print('Applies operation on all the files with specified ext. to the destination path specified:')
scandir=input('Enter the path to scan(absolute or relative path):')
print(f'You entered :{scandir}')
choice = input('Enter operation to perform(move|copy|delete|list):').lower()
EXCLUDE=['Android','DCIM', 'documents', 'WhatsApp', 'MIUI','bluetooth'] #exclude some system folder on android . Add your one also. 
if choice == 'copy' or choice =='move':
    dest=input('Enter the destination path(absolute or relative path):')
    print(f'You entered :{dest}')
    EXCLUDE.append(dest)
DATA_TYPES=input('Enter Data types to filter(comma-seprated)(ex.- jpg,txt): ').split(',')
files2=[]
print('*'*5,'FINDING FILES')
for root, dirs, files in os.walk(scandir):
    for file in files:
        for typ in DATA_TYPES:
            if file.endswith(typ):
                a = join(root,file)
                print(root, end='')
                print('-->',file)
                files2.append(a)
    for directory in EXCLUDE:
        if directory in dirs:
            dirs.remove(directory)

            
def copy_move_files():
    start=perf_counter()
    print('-'*5, f'Trying To {choice.capitalize} Files')
    if not os.path.isdir(dest):
        print(f'{dest} does not exists')
        print(f'Creating {dest} directory')
        os.mkdir(dest)
    else:
        print(f'{dest} exists')
    for file in files2:
        fpath=os.path.join(dest,os.path.split(file)[-1])
        try:
            if not os.path.exists(fpath):
                if choice=='move':
                    
                    shutil.move(file,dest)
                    print(f'{file.split("/")[-1]} Moved Successfully')
                if choice=='copy':
                    shutil.copy(file,dest)
                    print(f'{file.split("/")[-1]} Copied Successfully')
            else:
                print(f'{file.split("/")[-1]} Already in destination folder')
        except shutil.SameFileError:
            print(f'{file.split("/")[-1].strip()} Already Exists in the destination directory. Add the Destination directory to EXCLUDE ')
    end = perf_counter() - start
    print(f'Operation took {end} second(s)')
      
            
def delete_files():
    print('-'*5, 'Trying To Delete Files')
    for file in files2:
        os.remove(file)
        print(f'{file} deleted')


if choice == 'copy' or choice=='move':
    copy_move_files()
elif choice == 'delete':
    delete_files()
else:
    print('No valid or "list" option detected\nOnly listing Files')
print('Exiting the program Now')
