The script below should open all the files inside the folder 'pruebaba' recursively but I get this error:
Traceback (most recent call last):
File "/home/tirengarfio/Desktop/prueba.py", line 8, in f = open(file,'r') IOError: [Errno 21] Is a directory
This is the hierarchy:
pruebaba
folder1
folder11
test1.php
folder12
test1.php
test2.php
folder2
test1.php
The script:
import re,fileinput,os
path="/home/tirengarfio/Desktop/pruebaba"
os.chdir(path)
for file in os.listdir("."):
f = open(file,'r')
data = f.read()
data = re.sub(r'(\s*function\s+.*\s*{\s*)',
r'\1echo "The function starts here."',
data)
f.close()
f = open(file, 'w')
f.write(data)
f.close()
Any idea?
Use os.walk
. It recursively walks into directory and subdirectories, and already gives you separate variables for files and directories.
import re
import os
from __future__ import with_statement
PATH = "/home/tirengarfio/Desktop/pruebaba"
for path, dirs, files in os.walk(PATH):
for filename in files:
fullpath = os.path.join(path, filename)
with open(fullpath, 'r') as f:
data = re.sub(r'(\s*function\s+.*\s*{\s*)',
r'\1echo "The function starts here."',
f.read())
with open(fullpath, 'w') as f:
f.write(data)
