python web programming for PHP programmers

[Nikola Skoric]

I0m a python newbie with PHP background. I've tried to make a web app
from one of my python scripts (which I haven't done before) and I
ended up with:

<?php
echo shell_exec("python foobar.py");
?>
which works really nice :-D

For some reason I can't find no "quick and dirty python web
programming tutorial for PHP programmers" on google. :-D I don't need
a general python tutorial, I just need a tutorial on how to make a
hello world server side script with python. Any suggestions?

Try googling mod_wsgi. While "real" python web-programming is usually
done a bit different (django, turbogears, pylons and lots of others I
forgot), I think it comes close to what a PHP-programmer would expect
how a webapp begins.

It boils down to a python-file saying


def application(environ, start_response):
status = '200 OK'
output = 'Hello World!'

response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)

return [output]


Well, I did the googling - here you have a starter:


http://code.google.com/p/modwsgi/

See the configuration-section.

Clever

Python can work in a similar way to PHP if your server supports it,
but Python also allows you to create the server itself.

See http://webpython.codepoint.net/cgi_hello_world for a very
primitive way (and docs here: http://docs.python.org/dev/library/cgi.html
).

A better way, that uses a trivial Python-based server:

hello.py
---
from wsgiref.simple_server import make_server
def hello_app(environ, start_response):
start_response("200 OK", [('Content-Type','text/plain')])
return "Hello world!"
httpd = make_server('', 8000, hello_app)
print "Serving HTTP on port 8000..."
httpd.serve_forever()
---

Then:
$ python hello.py
Serving HTTP on port 8000...
localhost - - [24/Dec/2008 13:11:32] "GET / HTTP/1.1" 200 12
(see http://docs.python.org/dev/library/wsgiref.html#module-wsgiref.simple_server
)

You can use better Python-based servers with handy features for
testing:
http://projects.wagner-flo.net/wsgi-serve/
http://pypi.python.org/pypi/James/0.7.1


Now, to ease things, you can have Python working more like PHP.

First, server support. What HTTP server are you using? For starting
up, mod_python (http://www.modpython.org/) isn't that bad, but there
are better alternatives: http://code.google.com/p/modwsgi/ ,
http://pypi.python.org/pypi/python-fastcgi/1.1 and http://python.ca/scgi/

Then, there are many ways of getting the PHP feel (embedding in pages,
etc.):
