How to get progress in python script.

[Rolando Cañer Roblejo]

Hi all,

Please, I need you suggest me a way to get statistics about a progress
of my python script. My python script could take a lot of time
processing a file, so I need a way that an external program check the
progress of the script. My first idea was that the python script write a
temp file showing the progress and the external program can check that
file, but I think might happen file read/write locking issues.

Thanks.

The external program should open the progress file for read only, so I
wouldn't think file locking would be an issue.

Hello,

One easy way would be to use a RPC system. Pyro implements one of them.
See http://packages.python.org/Pyro4/tutorials.html

This could be achieved in very few lines.

Your script create a thread in which it serves the remote requests.

xmlrpclib is another popular RPC package.

Another solution is to use a web server (sounds overkill but it isn't).

A lot of python web frameworks allow you to create such server in very few lines. look at http://www.cherrypy.org/ for instance, use their 'hello word' example and replace the 'hello word' by the current script progress and you're done.

Would the Python profiler meet your need?
