capturing ESC, page up/down in Python

[jordilin]

Is there any way to capture the keyboard events ESC, page up (next
page), page down (previous page) in Python?. I mean, how can I capture
if user presses one of those keys in a terminal based application? I
was thinking about pygame.key.get_pressed from the pygame module, but
I don't feel really happy about importing pygame in a non related game
project.

RotatingFileHandler key error when parsing a logging config file

[jordilin]

Hi,
 I've a config for logging where I set up a file rotation with
handlers.RotatingFileHandler and when the app parses the logging
config it says keyError when trying to parse that section
('RotatingFileHandler' is not defined). Curiously enough, I can do
import logging and from logging.handlers import RotatingFileHandler.

Example:

[handlers]
keys=handlers.RotatingFileHandler

[formatters]
keys=simpleFormatter

[logger_root]
level=DEBUG
handlers=handlers.RotatingFileHandler

[handler_handlers.RotatingFileHandler]
class=handlers.RotatingFileHandler
level=DEBUG
formatter=simpleFormatter


I'm using python 2.4 in the servers. I'm having this in a particular
one, which seems like there must be some kind of configuration error.
Any suggestions,
Thanks

Re: postprocessing in os.walk

[jordilin]

Well, you could use the alternative os.path.walk instead. You can pass
a callback as a parameter, which will be invoked every time you
bump into a new directory. The signature is os.path.walk
(path,visit,arg). Take a look at the python library documentation.

Matplotlib is the one. There is Google Chart api which seems fairly
easy to understand and use thanks to pygooglechart bindings.
