Trabajando con archivos y directorios con Python¶ |
|
Listado de archivos en un directorio¶ |
|
|
|
Para buscar todos los archivos con una extensión, por ejemplo .jpg: |
|
|
|
import glob |
|
lista = glob.glob("*.jpg") |
|
|
|
Para listar todos los archivos de un directorio: |
|
|
|
import os |
|
ficheros = os.listdir('/home/alumno/ejercicios/python') # linux |
|
ficheros = os.listdir(r'c:Documents and SettingsalumnoEscritorioejerciciospython') #windows: cuidado con el caracter |
|
|
|
Directorio actual: |
|
|
|
os.getcwd() |
|
os.curdir |
|
|
|
Tipos de ficheros¶ |
|
|
|
print michero, 'es un', |
|
if os.path.isfile(mifichero): |
|
print 'fichero' |
|
if os.path.isdir(mifichero): |
|
print 'directorio' |
|
if os.path.islink(mifichero): |
|
print 'enlace' |
|
|
|
Último acceso a un fichero¶ |
|
|
|
ultimo_acceso = os.path.getatime('foto.jpg') |
|
ultima_modificacion = os.path.getmtime('foto.jpg') |
|
tiempo_en_dias = (time.time()- ultimo_acceso)/ (60*60*24) |
|
print tiempo_en_dias |
|
|
|
Eliminar ficheros y directorios¶ |
|
|
|
os.remove('mifoto.jpg') |
|
for foto in glob.glob('*.jpg') + glob.glob('*.tif'): |
|
os.remove(foto) |
|
|
|
Eliminar directorio: |
|
|
|
import shutil |
|
shutil.rmtree('midirectorio') |
|
|
|
Copiar y renombrar ficheros¶ |
|
|
|
import shutil |
|
shutil.copy(mifichero, copiafichero) |
|
|
|
# copia también tiempo de último acceso y última modificación |
|
shutil.copy2(mifichero, copiafichero) |
|
|
|
# copia un árbol de directorios |
|
shutil.copytree(raiz_de_directorio, copia_directorio) |
|
|
|
Manipulando los paths y nombres¶ |
|
|
|
Rutas |
|
|
|
>>> os.path.split('/home/alumno/python/ejercicios/ej1.py') |
|
('/home/alumno/python/ejercicios', 'ej1.py') |
|
>>> os.path.basename('/home/alumno/python/ejercicios/ej1.py') |
|
'ej1.py' |
|
>>> os.path.dirname('/home/alumno/python/ejercicios/ej1.py') |
|
'/home/alumno/python/ejercicios' |
|
|
|
Extensiones |
|
|
|
>>> os.path.splitext('pelicula.avi') |
|
('pelicula', '.avi') |
|
|
|
Crear y moverse entre directorios¶ |
|
|
|
directorioOriginal = os.getcwd() |
|
directorio = os.path.join(os.pardir, 'miNuevoDir') |
|
if not os.path.isdir(directorio): |
|
os.mkdir(directorio) |
|
os.chdir(directorio) |
|
... |
|
os.chdir(directorioOriginal) # vuelve al directorio inicial |
|
os.chdir(os.environ['HOME']) # cambia al directorio home |

#26. ficheros |
|
''' |
|
Archivos |
|
|
|
Los ficheros en Python son objetos de tipo file creados mediante la función open (abrir). |
|
Esta función toma como parámetros una cadena con la ruta al fichero a abrir, que puede ser relativa o absoluta; una cadena opcional indicando el modo de acceso (si no se especifica se accede en modo lectura) y, por último, un entero opcional para especificar un tamaño de buffer distinto del utilizado por defecto. |
|
|
|
|
|
El modo de acceso puede ser cualquier combinación lógica de los siguientes modos: |
|
|
|
‘r’: read, lectura. Abre el archivo en modo lectura. |
|
El archivo tiene que existir previamente, en caso contrario se lanzará una excepción de tipo IOError. |
|
‘w’: write, escritura. Abre el archivo en modo escritura. |
|
Si el archivo no existe se crea. Si existe, sobreescribe el contenido. |
|
‘a’: append, añadir. Abre el archivo en modo escritura. |
|
Se diferencia del modo ‘w’ en que en este caso no se sobreescribe el contenido del archivo, sino que se comienza a escribir al final del archivo. |
|
‘b’: binary, binario. |
|
‘+’: permite lectura y escritura simultáneas. |
|
‘U’: universal newline, saltos de línea universales. |
|
Permite trabajar con archivos que tengan un formato para los saltos de línea que no coincide con el de la plataforma actual (en Windows se utiliza el caracter CR LF, en Unix LF y en Mac OS CR). |
