Hello,
I have written a Python package to read from and write to a serial
device that uses short telegrams to communicate with sensors and
actuators. My classes include one to model the transceiver (it
establishes the serial connection using
serial.aio.create_serial_connection) and one for the tel

The way you describe it, it sounds like it would require a change to the
server. I can only modify the client. I'll try t

I have been thinking about that.
There is a slight risk that the client m

Hi,
I have a Python application that communicates with a server via telnet.
Host and port of the server are supplied by the user when the
application is started.
How can I determine from within the application whether the server's
host actually is the local host? (In that case I could implement a

I have asked the PSF for help regarding the implications of the license
status of code from sre_parse.py and the missing license statement in
sre.py. I'll happily report their answer to the list I they don't reply

At least partially, my confusion seems to be caused by the dichotom
Hello,
I have written a small utility to locate errors in regular expressions
that I want to upload to PyPI. Before I do that, I would like to learn
a litte more about the legal aspects of open-source software. What would
be a good introductory reading?
Plus, I have one very specific question: I

sub-expression causing the non-match. My idea is to use a parser to
create a tree representing the complete regular expression. Then I could

I would like to use Python on a router, an Edimax BR-6104K, running OpenWrt
(http://www.openwrt.org). While I probably won't need most of the fancier stuff
in Python, serial I/O and threads should be supported.
The router is based on the ADM5120P, has 2MB of flash and 16MB of RAM, so the
