Try except - bug?

[Askari]

Hi,
I have a problem with try except :
example
============
try:
print "bou!"
raise "ha!"
except:
try:
fileDest.close()
except NameError:
print "error"
except:
import traceback
traceback.print_exc(file=sys.stdout)
============
If I run this example alone, I have no problem :
result
============
bou!
error
============

but I can't understand why doesn't work in my program :
http://www.cvm.qc.ca/9974331/Temp/crypte.py
(too long for a copy and paste)
(note : it's at line 353)
(note : the language of this program is in french, sorry)

when I run my program, I have this error :
============
Traceback (most recent call last):
File "C:\Documents and Settings\Assembleur_Man\Bureau\Crypte.py",
line 355, in crypte
fileDest.close()
NameError: global name 'fileDest' is not defined
============

but I know that 'fileDest' is not always defined but I put this line
in a try-except!? :-( :-S

Ops! For test (to do the error), you must click on button "crypter!" with
blank textField

That's strange, because there is no fileDest.close() on line 355. Are you
sure the message and the code you are showing us correspond?

The program runs fine and displays a dialogue with "!ERREUR! :: Vous devez
avoir un code pour l'encryption.".

It's at 355 or 363 the error...

============
Traceback (most recent call last):
File "C:\Documents and Settings\Assembleur_Man\Bureau\test.py", line 363, in c
rypte
os.remove(destination)
OSError: [Errno 2] No such file or directory: ''
============

at line 355 you have : "fileDest.close()"
and at line 363 you have : "os.remove(destination)"

What is your version of python? (I have 2.3.2)
Do you have "Traceback" message in console (when you see the dialog)?

Askari:

OSError: [Errno 2] No such file or directory: ''

If I'm not mistaken this is another exception!?

at line 355 you have : "fileDest.close()"

No, line 355 of http://www.cvm.qc.ca/9974331/Temp/crypte.py is:

#afficher confirmation

and at line 363 you have : "os.remove(destination)"

No, line 363 of http://www.cvm.qc.ca/9974331/Temp/crypte.py is:

pass

What is your version of python? (I have 2.3.2)

I use UltraEdit 8.0 on Windows XP to count the line numbers.

euh.... I use UltraEdit 10.10 and "#afficher confirmation" is at line 349
(it's the same numero in IDLE). Are you sure that your UltraEdit is
correct? Check the line in IDLE, it's the same?

Batheme! I didn't know that the exception rest in memory after a "catch".
Finaly, it's my mistake with use of "sys.exc_info()" at line 368.

But for # of line; check your ultraedit. Are you sure that the line 1 is
"#! d:/python23/python" ?
