melhorar script


Recommended Posts


Estou a tentar fazer um programa que recebe dois paths, lê as imagens que estão no primeiro path, abre-as, depois converte-as para 'png' e salva-as no segundo path.

Epá, fiz isto mas obviamente que isto está à pedreiro e não consegui usar o Pathlib devidamente. O que é que preciso mudar para isto não ficar assim tão à pedreiro?

Para já nem liguei ao facto de eu verificar os argumentos passados depois de usar o primeiro argumento... Agora quero é perceber como usar o Pathlib para guardar as imagens numa nova pasta.

import sys
from pathlib import Path
from PIL import Image

# grab first and second argument
# check if new/ exists, if not, create it
# loop through the folder and convert to png
# save to the new folder

def proc_args():
    """Process arguments from command line"""
    if len(sys.argv) < 3:
        print('Not enough parameters!')
        newpath = Path(sys.argv[2])
            newpath.mkdir(parents=True, exist_ok=False)
        except FileExistsError:
            print(f'{newpath} already exists!')
        except IOError as ioerr:
            print(f'{ioerr}: {newpath} could not be created')

    return newpath

def conv_imgs(pold_p, pnew_p):
    """Loop over files in folder"""
    for item in Path(pold_p).rglob('*.jpg'):
        img = Image.open(item)
        noext = item.with_suffix('')
        newext = noext.with_suffix('.png.png')
        tmp = Path(newext).stem
        img.save(Path(pnew_p).joinpath(tmp), 'png')

def main():
    """Main Function"""
    old_path = Path(sys.argv[1])
    new_path = proc_args()
    conv_imgs(old_path, new_path)

if __name__ == '__main__':
