One way to do this is to put a redirect in the response to the login page. This will make the 
browser go to the second page. This page tells how:
http://www.instant-web-site-tools.com/html-redirect.html

Note that you are not actually password protecting your second page; there is nothing to prevent a 
user from navigating directly to the second page. For real protection the second page needs to check 
if the user is logged in using some kind of session mechanism, and redirect to the login page if the 
user is not authenticated. There are many Python web frameworks that can help with this.

BTW you should try using triple-quoted strings for your blocks of HTML, then you can just type 
literally what you want, no embedded 'print' or '\n' or escaped quotes, e.g.

    print """\
<HTML>
<HEAD>
     <TITLE>Menu List</TITLE>
</HEAD>
<BODY BGCOLOR = white>
     <H3>Please choice a operation.</H3>
<FORM METHOD = post ACTION = "index1.cgi">
"""
etc.
