Re: a clean exit

Hello everybody,
I wrote a bot for telegram which consists of some processes of which the
main ones are:
- the main process: a list of callback functions
- a second process: managed with a message queue
- a third process: started by the library I use (python-telegram-bot)
which is used for the event/error log ('logging' module).
The problem is that sometimes I get an error from the library (python-
telegram-bot) via logging that my bot has no way of intercepting. The
error is "connection reset by pear" after which my program is no longer
called and I need to restart it. Typically this happens when Telegram
runs an update.
In any case I can know this error because, to write a log in a telegram
channel, I inherit the 'emit' function of the 'logging.Handler' class.
Hoping to have explained clearly enough the context in which the program
receives information about the error (we are inside a process not
launched directly from the main program), my question is: do you have
advice on how I can close my program in the way as clean as possible in
a easy way?
Thanks in advance.
Thanks to both of you for the replies. I know the rules you described to
me for process synchronization but unfortunately, due to the structure
of the library I am using, I cannot apply them. I can't even use
try/except because the library, when the error occurs, displays it with
the loggin libraries and no longer calls any of the callback functions
my program is composed of. To understand when the error occurs, my only
possibility is to intercept the logging, read the error string and,
if it is not one of mine (mine all start with ":"), to
close the program. Following some examples on the web I also configured
a function to handle the error:
'''
dispatcher.add_error_handler(callback=fallback_error,
run_async=True)
'''
but unfortunately after getting that error the library seems to hang and
doesn't call my callback function.
I was actually hoping to get some tricks to shut down all processes as a
suggestion. Could I, for example, create a global list containing the
ids of the processes I started and then kill each of them? Can it make
sense?

The problem is due to the values of Sensors, TestStrips and SampleNumber
being strings; what you want is for them to be lists, as in the
assignments you commented out. And since the data from the file is read
in as strings, you have to cast the elements of the Sensors and
TestStrips lists to integers, since you want the numerical values. The
following code does the job:
Sensors = []
TestStrips = []
SampleNumber = []
x = 1
SensorNumber = input("Enter senaor number: ")
with open("_EXCEL-FILE.txt", 'r') as infile:
for lineEQN in infile:
if (lineEQN[0:1]== "."):
SN = lineEQN[44:48].strip()
if (SensorNumber == SN):
SN = x
SampleNumber.append(SN)
sv = lineEQN[25:29].strip()
Sensors.append(int(sv))
tv = lineEQN[32:37].strip()
TestStrips.append(int(tv))
x += 1
labels = SampleNumber
Add the rest of your code from the second half to make the desired bar
chart.

First off, you'll want to post code in a way that keeps the
formatting, otherwise it becomes very hard to read.
But the immediate problem here is that Popen takes an array of command
arguments, NOT a shell command line. You cannot invoke ls and pipe it
into awk this way.
Don't think like a shell script. Python has very good
directory-listing functionality, and you will very very seldom need to
shell out to pipelines. Figure out what you actually need to learn
from the directory listing and get that information directly, rather
than trying to use two external commands and text parsing. It's far
FAR easier, cleaner, and safer that way.

Alas, the python-list is text only, and attachments are discarded.

Alas, the python-list is text only, and attachments are discarded. Is your programme small enough (one file, not insanely long) to just include inline in your next message? Have you printed the variables generated by your code? _Are_ they the same as the hardcoded values? You may want to graph different stuff, but start by trying to exactly reproduce the hardcoded value, but extracted from the file.

I am going though a struggle with this and just don't see where it fails. I am using the Dual Bar Graph.py program from https://matplotlib.org/stable/gallery/index.html website. The file from the web site works so that shows that all my installations are complete. My program, LibreGraphics 05.py program runs but the graph is all smutched up.

When you run the program, choose 112 when prompted. You will see the values of the variables I want to pass to the graph section of the code. If the values are hardcoded, the graphs look good. When the variables generated by my section of the code, it does not. I am not sure what more to explain. Please help me Steve I am attaching a zip file. I hope it gets through.
