如何使用python3将路径中的文件夹移动到Windows中的另一个路径？

Question

I need a script to move all contents from source folder and create/replace into destination folder without removing any existing files/folders in destination. The contents of test1 folder will be a html file along with some images in png format.

source path : C:\\Users\\USERNAME\\Documents\\LocalFolder\\reports\\v2
source folder Name : test1

Destination path : T:\\remoteReports\\myTests Path to be created while copying: \\LocalFolder\\reports\\v2
Folder to copy from source into destination : test1

final path in destinaton: T:\\remoteReports\\myTests\\LocalFolder\\reports\\v2\\test1

I have taken a piece of code from stack overflow and using it for my application but running the script is not creating the path and folder in the destination.

import time
import os
import random
import shutil
import pathlib
def move_files(root_src_dir,root_dst_dir):
print(root_src_dir)
print(root_dst_dir)
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.move(src_file, dst_dir) 
 srcPath = os.path.join("C:", "Users", os.getlogin(),"Documents", "LocalFolder", "v2", "test1")
 dstPath = os.path.join("T:", "remoteReports", "myTests", "LocalFolder", "v2", "test1")
 move_files(srcPath,dstPath )

It will be helpful if someone can guide me with this !

You can use pathlib to copy all files from one folder to another:

from pathlib import Path
from shutil import copy

src = Path(r"C:\Users\USERNAME\Documents\LocalFolder\reports\v2")
dst = Path(r"T:\remoteReports\myTests\LocalFolder\reports\v2")
for file in src.iterdir():
    if file.is_file() and not (dst / file.name).is_file():
        copy(file, dst)

If you want to copy whole tree including sub directories and it's content, you can apply os.walk() :

from pathlib import Path
from os import walk
from shutil import copy

src = Path(r"C:\Users\USERNAME\Documents\LocalFolder\reports\v2")
dst = Path(r"T:\remoteReports\myTests\LocalFolder\reports\v2")
for dir_name, _, filenames in walk(src):
    src_path = Path(dir_name)
    dst_path = dst / src_path.relative_to(src)
    if not dst_path.is_dir():
        dst_path.mkdir()
    for file in filenames:
        dst_file = dst_path / file
        if not dst_file.is_file():
            copy(src_path / file, dst_path)

Or you can make function from code I've suggested firstly and use it recursively:

from pathlib import Path
from shutil import copy

def copy_folder(src_path, dst_path):
    if not dst_path.is_dir():
        dst_path.mkdir()
    for file in src_path.iterdir():
        if file.is_dir():
            copy_folder(file, dst_path / file.relative_to(src_path))  # recursion
        elif file.is_file() and not (dst_path / file.name).is_file():
            copy(file, dst_path)

src = Path(r"C:\Users\USERNAME\Documents\LocalFolder\reports\v2")
dst = Path(r"T:\remoteReports\myTests\LocalFolder\reports\v2")
copy_folder(src, dst)

BUT You don't really need to implement all this manually, because shutil.copytree() already exists and does exactly the same that all options I've provided before. Important notice: you should pass dirs_exist_ok argument to not throw an exception if directory in destination path already exists.

from shutil import copy, copytree
from os.path import exists

src = r"C:\Users\USERNAME\Documents\LocalFolder\reports\v2"
dst = r"T:\remoteReports\myTests\LocalFolder\reports\v2"
copytree(src, dst, copy_function=lambda s, d: not exists(d) and copy(s, d), dirs_exist_ok=True)

Here I've used lambda which check does file already exist to not overwrite it, you can omit this parameter if you don't care that files will be overwritten.

If you want to move all files, you can passshutil.move() to copy_function :

from shutil import move, copytree
...
copytree(src, dst, copy_function=move, dirs_exist_ok=True)

It'll move all files, but leave tree directory. If you want to copy all directory tree and delete it from source, you can call shutil.copytree() and shutil.rmtree() :

from shutil import copytree, rmtree
...
copytree(src, dst, dirs_exist_ok=True)
rmtree(src)
