Check the file extension and change its directory

Question

I’m having trouble with a python script that checks if there are files with a specific extension in the directory and moves the whole directory to another destination

This is a test to automate the process of moving a directory to another place depending on its extension, but I can only accomplish this if all the files have the same extension, otherwise, even if there is only one file with the desired extension it does not perform directory change.

Directory contents 'testar_mover_directory':

text file.txt

python file.py

import os, shutil


def verificar_dir(diretorio, extensao, destino):
    if (os.path.exists(diretorio) == True):
        for pasta, subpastas, arquivos in os.walk(diretorio):
            for arquivo in arquivos:
                extensao_arquivo = arquivo.endswith(extensao)
                if (extensao_arquivo == True):
                    result = ('Existem arquivos com a extensão {} na pasta').format(extensao)
                    if (os.path.exists(destino) == True):
                        shutil.move(diretorio, destino)
                    else:
                        result = 'O diretório de destino não existe'
                else:
                    result = ('Não existem arquivos com a extensão {} na pasta').format(extensao)
        return print(result)

    else:
        print('Este diretório não existe')

diretorio = input('Qual é o diretório que você deseja verificar? ')
extensao = input('Qual é a extensão que você procura? ')
destino = input('Qual será o destino deste diretório? ')
print('')

verificar_dir(diretorio, extensao, destino)

Example: I have a 'teste_mover_directory' folder on the desktop with '.txt' and '.py' files and want to move it to the 'Projects' directory, but the script does not make the change even if there is a '.py' file inside the folder.

Answer 1

For versions equal to or greater than 3.4 of the language use the package pathlib to manage directories and files. Its API is more direct and simple than the one provided by the package os.

1. To open a directory, use foo = pathlib.Path('./foo');
2. To search for files with a certain extension, use foo.glob('*.py');
3. If you return at least one file, rename the directory;

In code it would look something like:

from pathlib import Path

foo = Path('foo')

for _ in foo.glob('*.py'):
    foo.rename('bar')
    break
else:
    print('Nenhum arquivo .py encontrado')

So if you own the directory:

/foo
    main.py

When running the program you will have

/bar
    main.py

But beware of running conditions if there are multiple processes manipulating the same directory in parallel.
