Error message: Traceback (most recent call last): File "TestClean.py", line 12, in raw = urlopen(url).read() File "/usr/lib/python2.7/urllib.py", line 87, in urlopen return opener.open(url) File "/usr/lib/python2.7/urllib.py", line 208, in open return getattr(self, name)(url) File "/usr/lib/python2.7/urllib.py", line 463, in open_file return self.open_local_file(url) File "/usr/lib/python2.7/urllib.py", line 477, in open_local_file raise IOError(e.errno, e.strerror, e.filename) IOError: [Errno 2] No such file or directory: 'paroles-a-beautiful-lie.html'

Answer 1

Error message indicates a lack of file. os.walk returns only the name of the file, but not the full path to it. 1) Take the path = os.path.join(subdir, file) 2) Read the file open(path).read() without urlopen

Answer 2

It is well clear from the Traceback that it is not able to find 'paroles-a-beautiful-lie.html' file. I would suggest you to go step by step.

1. Comment the code below 'print url'.
2. Check whether you are getting proper url.
3. Then proceed with your next step - finding process.
