Imagine for instance, that you have an HTML file where you want to print a current timestamp when the page is displayed. A simple way to do this would be to just give your HTML file another extension (e.g. .tmpl, short for template). Keep the file as it is, just put the text %(timestamp)s in the place(s) where you want your timestamp to appear in the HTML file. In your CGI script you can then do something like this: #!/usr/bin/python -u import time print "Content-type: text/html\n" text = open('myfile.tmpl).read() print text % ('timestamp':time.asctime()) The inital Content-type line is important, and it must be followed by a blank line before the actual content. Look at the cgitb module too. Instead of the common Python % interpolation, you could use string.Template (with a current Python) or one of the many templating systems around. Since your needs are likely to grow, you might also want to have a look at one of the many tool kits for Python and the web. Right now, it seems that django and turbogears are the most popular. Cherrypy and web.py are somewhat smaller and simpler systems. Unless you use one of these tool kits, your homegrown code might turn into yet another web tool kit eventually, and we have enough of them already... (Too many I'd say...) You should also note that traditional CGI scripts are rather slow with Python, since Python's startup time is significant. A system where the Python interpreter is already running, as mod_python embedded in Apache is faster. But by all means, try it as CGI. It might well be enough for your needs. It's been ok for me. -- http://mail.python.org/mailman/listinfo/python-list
