python - How can I display environment variable

I code in python, and I have two python
files.
In the first I make
:

import cgi, cgitb,
            os
export REMOTE_ADDR

def main(addr,
            name):


 t =
            open('recei.py').read()

 having =
            string.Template(template).substitute(
 name = name,
 addr =
            cgi.escape(os.environ["REMOTE_ADDR"])

            )

in the second python
file I have my HTML code ( I put only a part of the form )
:

            name="sendData" method="get" action="echo
            ${addr}">

but I
have a big error
:

File "./send.py", line 12, in
            
 main(addr, name) 
 File "./send.py", line 45, in
            main
 addr = cgi.escape(os.environ["REMOTE_ADDR"])

 File
            "/usr/lib/python2.6/UserDict.py", line 22, in __getitem__
 raise
            KeyError(key)
KeyError:
            'REMOTE_ADDR'
