By the way, I stumbled upon PythonJS -- which proposes some nice tools: Flowchart from code generation realtime http://pyppet.blogspot.com/2014/02/code-visualization.html - Ability to export to Android (which attracs youth's attention ;) http://pyppet.blogspot.com/2014/02/pypubjs-exports-to-android.html On Tue, Jan 29, 2013 at 11:13 PM, Andre Roberge <andre.roberge@gmail.com>wrote:

Regarding the original question, about putting text adventures on the web, it's a funny thing, because that's what I've had on my mind since I heard about Brython. Initially it didn't even have print(), and to me that was a basic requirement. so I created a webprint for brython ( http://raspberry-python.blogspot.com/2012/12/brython-browser-python.html ), but then Pierre (the author) added print(). The next piece of the puzzle was the raw_input() (or in this case input() since Brython is Python 3.x ). Pierre, Andre (Roberge, fellow edu-sig member) and I went through various discussions on how this could work. In the end, I had to go back to my original thought of having input() bringing up a web browser prompt (javascript prompt) so the call would be blocking, to flow just like a Python script.
To test this, I grabbed a simple python text adventure from a blog ( http://livingcode.org/entries/2008-02-22_simple-text-adventure/ ) and plugged it in the web page, with minimum change, namely to convert it to Python 3.x syntax. The purpose of getting code I didn't write to test the idea, was that I knew how to code around the limitations of a web browser (event driven vs the linear approach of a typical Python script), so if my code ran ok, it wouldn't prove the suitability of the solution. So the code from the blog ran, but it's not 100% what one would expect. You can check it out for yourselves here (it's my Brython playground, on free hosting so it's not particularly fast to answer):
Having just tried it, I noticed a problem with it that I had not anticipated when thinking of using prompt for input. the information written in the textarea (?) needs to be scrolled up; however, the prompt prevents a user from doing so. .
A more proper way of doing this does require eliminating the while True: loop and replacing it with a function, and moving the input to the end of the function:

This works much better. The way I would describe, without looking at the
code, would be like a state machine. The "world" is stored as an object; when the user enters a command, a single function call is issue [ "update(user_input)"] and some feedback is given. Impressive.

Still, it is close to a solution.
