I found the following solution to use idle on the raspberry pi
as sudoer (which is necessary or at least comfortable when programming the
GPIO)
1. Open a terminal
2. type cd ~/Desktop
3. type touch idle_as_root
4. type nano idle_as_root
5. type in sudo idle
6. exit nano
7. type in sudo chmod +x id

I have a python-program which I want to perform its task first, then
switch to
the python console to experiment with further commands, using what was
already
defined in the python-program.
I want this as an alternative for what I do now (but which is not very
efficient):
I start the python-console

I have an ethernet-rs232 adapter which allows me to connect to a measurement
instrument by means of netcat on a linux system.
e.g. entering nc 10.128.59.63 7000
allows me to enter e.g.
*IDN?
after which I get an identification string of the measurement instrument back.
I thought I could accomplish

I'm trying to go through a tutorial on tkinter which has the code below as an

mouse here to quit" which works as expected but always shows the following

I'm writing some code to check whether an url is available or not,
therefore I make use of a wget-command in Linux and then check whether
this is successful (returning a 0) or not returning an 8
However the if then statement seems to give the same result in both
cases:

I have trouble with the code beneath to make an array with equally
spaced values
When I enter 100e-6 as start value, 700e-6 as end value and 100e-6 I
get the following result:
[ 0.0001 0.00022 0.00034 0.00046 0.00058 0.0007 ]
But I was hoping for:

The following test program which tries to communicate with a Keithley

The error may be obvious but finding this file and how to install it

I'm trying to control a programmable power supply via USB using
python.
After doing some googling I thought I should use PyVisa for this
purpose, so I installed it as follows:
tar xvfz PyVISA-1.4.tar.gz
cd PyVISA-1.4
python setup.py install
Installation seems to finish without errors.

I'm looking for a good introduction to object oriented programming
with Python. I am looking for an introduction which only refers to
Python. I have seen introductions where the authors make comparisons
to other languages such as C++ and Java, but as I don't know these
languages that doesn't help m

I'm trying to combine python-code made with QT4 designer with plain

Can anyone tell me what I have to add to the following code just to
open a file when clicking on the load-button and closing it by
clicking on the save button.
