I would like to have a USB pen drive, which can execute python scripts
including CGI versions, which I can take to any Windows PC and run
without having to install anything on the PC.
My days of hacking are past so I am looking for something very simple.
I would envisage a batch file which would ask if the USB web server
needed to be started or just python scripts and it would return the IP
address of the server or even some local host name such as 'bobserver'
which I could give it.
To the best of my knowledge you should be squared away if you have
Movable Python and the script below. Let me know whether it works for
you. (You might have to adjust the path somewhat.)
Movable Python:
http://www.voidspace.org.uk/python/movpy/
#!/usr/bin/python
"""
The CGIHTTPServer module
This is a simple HTTP server that can call external scripts through the
common gateway interface
(CGI).
Example: Using the CGIHTTPServer module
# File:cgihttpserver-example-1.py
If you are reading this, you have all the source code necessary to run
your own Web server.
Run this with Python.
Note: This script allows symlinks to places outside the document root.
