My Python Learning Journal: LPTHW

In this exercise we will make a web application from the Gothons game, which we made in exercise 46. To simplify the process of making a web application, we need a we need a web framework. For this exercise we will use lpthw.web, which is the same as the webpy framework.

I installed the web framework thus
pip install lpthw.web

Then I created a project for the web application by creating a directory in my projects directory:
ex50
/bin
app.py
/docs
/gothonweb
__init__.py
/templates
__init__.py
/tests

I just copied the code provided in LPTHW in app.py

I ran the webserver with 'python bin/app.py' and successfully loaded the url http://localhost:8080

However, I realized that lpthw.web was not installed in my virtualenv as I would have expected it to be. It was actually installed in /usr/local/lib/python2.6/dist-packages/ This seems strange and incorrect to me. I am not quite sure what went wrong, so I asked a question on StackOverflow.

The code for this exercise is embedded below:

	import web

	urls = (
	'/', 'index'
	)

	app = web.application(urls, globals())
	render = web.template.render('templates')

	class index:
	def GET(self):
	greeting = "Hello"
	return render.index(greeting = greeting)

	if __name__ == "__main__":
	app.run()

	$def with (greeting)

	<html>
	<head>
	<title>Gothons Of Planet Percal #25</title>
	</head>
	<body>

	$if greeting:
	I just wanted to say <em style="color: green; font-size: 2em;">$greeting</em>.
	$else:
	<em>Hello</em>, world!

	</body>
	</html>
