| i dont know why that if statement errors.
Python statements that continue (if, while, try etc) end in a colon, so:
Oh iam very sorry.
Oh my God i cant beleive i missed a colon *again*:
I have corrected this:
#========================================================
# Collect filenames of the path dir as bytes
filename_bytes = os.listdir( b'/home/nikos/public_html/data/apps/' )
for filename in filename_bytes:
# Compute 'path/to/filename' into bytes
filepath_bytes = b'/home/nikos/public_html/data/apps/' + b'filename'
flag = False
try:
# Assume current file is utf8 encoded
filepath = filepath_bytes.decode('utf-8')
flag = 'utf8'
except UnicodeDecodeError:
try:
# Since current filename is not utf8 encoded then it
has to be greek-iso encoded
filepath = filepath_bytes.decode('iso-8859-7')
flag = 'greek'
except UnicodeDecodeError:
print( '''I give up! File name is unreadable!''' )
if flag == 'greek':
# Rename filename from greek bytes --> utf-8 bytes
os.rename( filepath_bytes, filepath.encode('utf-8') )
==================================
Now everythitng were supposed to work but instead iam getting this surrogate
error once more.
What is this surrogate thing?
Since i make use of error cathcing and handling like 'except
UnicodeDecodeError:'
then it utf8's decode fails for some reason, it should leave that file alone
and try the next file?
try:
# Assume current file is utf8 encoded
filepath = filepath_bytes.decode('utf-8')
flag = 'utf8'
except UnicodeDecodeError:
This is what it supposed to do, correct?

Look at the traceback.
It says that the exception was raised by:
query = query.encode(charset)
which was called by:
cur.execute('''SELECT url FROM files WHERE url = %s''', (filename,) )
But what is 'filename'? And what has it to do with the first code
snippet? Does the traceback have _anything_ to do with the first code
snippet?
