Validating Python - need doctype HTML strict

Tue Jul 11 16:09:39 EDT 2006

Thanks Ben,

As you can see it's my first try at Python...or any programming for
that matter.

I solved the problem of validation by adding three """ quotes after the
print command and before the body, as follows:

Thanks for clearing that up!

-----------------------

import time

#print HTTP/HTML header stuff
print """Content-type: text/html; charset=utf-8\n\n

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html
xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

<head>

<title>Current Time</title>

</head> <body>
"""

print

#print HTML body using Python-HTML hybrid script
print "<h1>Current Time</h1>"

print "<p>Right now, it is "

print "<strong>", time.asctime(), "</strong></p>"

print """<p>
    <a href="http://validator.w3.org/check?uri=referer"><img
        src="http://www.w3.org/Icons/valid-xhtml10"
        alt="Valid XHTML 1.0 Strict" height="31" width="88" /></a>
  </p>
"""

print "</body></html>"
