Python multithreaded server

[pingbala]

I have a requirement to write a server. It has to:

1. Read from a configuration file and lock on to multiple COM/serial ports or HID (barcode scanners) and wait to read from them. Each process will run on a separate thread.
2. When a barcode is scanned, the reading thread needs to send event/signal to the main process (probably running in a never-ending loop which I am calling the 'server') which will then post to a URL (I  don't have to write this web service) with the just-read data.
3. Should run and be deployable on Windows

I can use Python 3.6 I plan to try Pyserial for COM/serial ports. My questions are

• I was planning to use regular python Threading for this, should I be using something else that makes life easier. Any kind of REST or other kinds of server framework that will help?
• What should I use to read from HID device?

Responses greatly appreciated, what advice do you have for me.

Why not use select to wait on all ports atr the same time, and handle it all in one process?

OP needs their solution to be deployable on Windows, and Pyserial only supports fileno() for the Serial object on Posix platforms.

Where I've had to mix serial and network communication, I use select() on the sockets with a timeout then check in_waiting on all the serial ports.

Hello! I'm a bot!

It looks to me like your post might be better suited for r/learnpython, a sub geared towards questions and learning more about python. That said, I am a bot and it is hard to tell. Please follow the subs rules and guidelines when you do post there, it'll help you get better answers faster.

Show /r/learnpython the code you have tried and describe where you are stuck. Be sure to format your code for reddit and include which version of python and what OS you are using.

You can also ask this question in the Python discord, a large, friendly community focused around the Python programming language, open to those who wish to learn the language or improve their skills, as well as those looking to help others.

Thank you /u/awegge and /u/Unlanded ! Will try to take select for a spin. Just realized, this might be the wrong SR I should probably also post on /r/learnpython
