No idea how to parse "have no meaning calling them in plain our of a cgi 
environment"

But there were two problems with the code you faithfully copied from my 
earlier post.  One was already pointed out by feedthetroll, that I 
accidentally changed REMOTE_ADDR to REMOVE_ADDR.

The other one is perhaps more subtle; I replaced square brackets with 
parentheses.

So try again with:

  >>> import os
  >>> remadd = os.environ['REMOTE_ADDR']

I get an error:

Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "/usr/local/lib/python3.3/os.py", line 669, in __getitem__
     value = self._data[self.encodekey(key)]
KeyError: b'REMOTE_ADDR'


but presumably your machine actually has such an environment variable.

Isn't that mistake something  you could easily have caught?  Or were you 
just blindly pasting my bugs without understanding what I was trying to 
do with refactoring?

Anyway, I can't see any reason why the rest of the sequence shouldn't 
behave identically from a terminal as it does in CGI.
