Hi,
I have just written a python module to program the M232 measurement unit
from elv.
It has 8 digital I/O and 6 analog ports (0-5V). Works fine, although it

Furthermore the digital ports do not have enough power to switch a relay

Hi,
Before I reinvent the wheel I`d like to ask if someone has done this

The goal is to create a dynamic Tree View in HTML.

Hi,
given the dynamic nature of python I assume that there is an elegant
solution for my problem, but I did not manage to find it.
I have a file that contains for example on line:
['147', '148', '146']
when I read the file
f = file("I050901.ids").readlines()
I have a string
f[0] == "['147
the sense of this file is to make a list persistant quickly
and easily and human readable. Maybe pickleing is a third option?
