KeyError

[root...@gazeta.pl]

Hello.
Maybe someone will help me with this KeyError:

............................
Traceback (most recent call last):
File "C:\Python\tabla.py", line 929, in -toplevel-
tablesDirectory = tablesDirectoryPrefix + os.environ['REMOTE_ADDR']
File "C:\Python23\lib\os.py", line 417, in __getitem__
return self.data[key.upper()]
KeyError: 'REMOTE_ADDR'
..........................

Thanks for reading this.
R.

What trouble do you have? AFAICT, The key REMOVE_ADDR wasn't in the
dictionary, meaning that the environment variable doesn't exist.

Cheers,

Frans

Hi "R",

The only explanation I can give is that the environment varialbe REMOTE_ADDR
does not exist! Wrap your high-level code with try and except. Example:
try:

tablesDirectory = tablesDirectoryPrefix + os.environ['REMOTE_ADDR']

except KeyError:
# Code to handle the fact tht REMOT_ADDR does not exist.

Hope that this helps and is not just another infamous "Dermot Didn't Get It"
posting!

Cheers!!

That tabla.py of yours is certainly to be executed in a CGI environment. So
call it that way - or provide the neccessary environment by stuffing values

... or just replace os.environ['REMOTE_ADDR'] with
os.environ.get('REMOTE_ADDR', 'enter_default_here') to use a default in
case of missing REMOTE_ADDR ...

If a default value would be acceptable to the application (which is quite
likely), then this would be a much cleaner solution.
