Python 移动文件并重命名它（如果文件夹中存在）

我试图移动文件夹中的文件，但如果dest文件夹中存在此文件名，我希望将其重命名为（'name.py（1）'）

对于前两个文件，它工作得很好，但在那之后它崩溃了，但我不明白为什么

import os
import shutil
from airflow import AirflowException


uploadPath  = '/apps/manu/80_DATA/00_Loading/'
dirPath = '/apps/manu/80_DATA/04_Other/'

# print('coucou')
if(os.listdir(uploadPath)):
    for files in os.listdir(uploadPath):
        if not os.listdir(dirPath):
            shutil.move(uploadPath+files, dirPath+files)
            print('no need to rename, so i moved it ...', files)
        else:
            for files in os.listdir(uploadPath):
                addOne=0
                for dirFile in os.listdir(dirPath):
                    if files in dirFile:
                        newName = os.rename(uploadPath+files, dirPath+files+str(addOne))
                        addOne+=1
                        print('renamed in '+str(newName))
                shutil.move(uploadPath+files, dirPath+files)



else:
    print('No file')
    pass

错误是：

FileNotFoundError: [Errno 2] No such file or directory: '/apps/manu/80_DATA/00_Loading/coco.py' -> '/apps/manu/80_DATA/04_Other/coco.py1'

Thx帮助：）

您一直在列出文件

for files in os.listdir(uploadPath):     <<===== files
        if not os.listdir(dirPath):
            shutil.move(uploadPath+files, dirPath+files)
            print('no need to rename, so i moved it ...', files)
        else:
            for files in os.listdir(uploadPath):    <<===== files again

没有经过测试，但我想你已经开始工作了：-）

试试这个：

import os
import shutil
from airflow import AirflowException


uploadPath  = '/apps/manu/80_DATA/00_Loading/'
dirPath = '/apps/manu/80_DATA/04_Other/'

def unique_filename(file):
    duplicate_nr = 0
    base, extension = os.path.splitext(file)
    while os.path.exists(file):
        duplicate_nr += 1
        file = f'{base}({duplicate_nr}){extension}'
    return file

if(os.listdir(uploadPath)):
    for files in os.listdir(uploadPath):
        if not os.listdir(dirPath):
            shutil.move(uploadPath+files, dirPath+files)
            print('no need to rename, so i moved it ...', files)
        else:
            if os.listdir(dirPath):
                upload_files= os.listdir(dirPath)
                for upload_file in upload_files:
                    upload_file_path = os.path.join(uploadPath, upload_file)
                    dir_file_path = os.path.join(dirPath, upload_file)
                    dir_file_path = unique_filename(dir_file_path)
                    os.rename(upload_file_path, dir_file_path)
                    print('upld path', upload_file_path)
                    print('dir path', dir_file_path)
                    print('upld file', upload_file)
                    print('dir file', upload_files)

else:
    print('No file')
    pass

看起来你正在重命名循环中的文件，然后你又在尝试移动它。是的，我猜是这样，但什么时候会这样？因为第一个文件被重命名编辑不起作用，所以文件被删除，我不知道为什么，因为它被签入make_unique_filename upload_file_path=os.path.join（dirPath，upload_file）当然是错误的。很抱歉最后一个问题，为什么文件副本以字符串形式复制，file=coco.py，变成“coco（1.py）”？当我再次尝试“FileNotFoundError:[Errno 2]没有这样的文件或目录：'/apps/manu/80_DATA/00_Loading/coco（1.py'->'/apps/manu/80_DATA/04_Other/coco（1）（1.py'）–Filename（duplicate_nr）。ext是删除重复项的常用方法，因为它保留了原有的扩展名。.py文件保持为.py文件，这通常是最方便的。将（1）文件复制到已存在该（1）文件的目录时，会出现（1）（1）。当您将aaaa.bb多次复制到同一目录时，您将得到aaaa（1）.bb、aaaa（2）.bb等。。。只需玩一些简单的dir示例，看看会发生什么。顺便说一下：file_path=f'{base}{extension}（{duplicate_nr}'）应该按照您的方式重命名文件。upload_files=os.listdir（dirPath）

import os
import shutil
from airflow import AirflowException


uploadPath  = '/apps/manu/80_DATA/00_Loading/'
dirPath = '/apps/manu/80_DATA/04_Other/'

def unique_filename(file):
    duplicate_nr = 0
    base, extension = os.path.splitext(file)
    while os.path.exists(file):
        duplicate_nr += 1
        file = f'{base}({duplicate_nr}){extension}'
    return file

if(os.listdir(uploadPath)):
    for files in os.listdir(uploadPath):
        if not os.listdir(dirPath):
            shutil.move(uploadPath+files, dirPath+files)
            print('no need to rename, so i moved it ...', files)
        else:
            if os.listdir(dirPath):
                upload_files= os.listdir(dirPath)
                for upload_file in upload_files:
                    upload_file_path = os.path.join(uploadPath, upload_file)
                    dir_file_path = os.path.join(dirPath, upload_file)
                    dir_file_path = unique_filename(dir_file_path)
                    os.rename(upload_file_path, dir_file_path)
                    print('upld path', upload_file_path)
                    print('dir path', dir_file_path)
                    print('upld file', upload_file)
                    print('dir file', upload_files)
