I would like to set "errored" to False if the exception is a Timeout error. I'm a little confused how try except flows work in python here (and surprisingly couldn't find any doc clarifying this - if anyone has one regarding how the blocks are executed please feel free to link), like if multiple exception blocks are true, do they all execute? Or just the first one? I assume the below doesn't work because we don't have access to 'r'

try:
    r = request(
        method="POST",
        ...
    )
    r.raise_for_status()
    resp = r.json()
    errored = False

except Exception as e:
    resp = _parse_json(e)
    errored = True
    if r.Timeout:
        errored = False

And the below is the effect I want, just not sure if it works as intended with the try/except flow

try:
    r = request(
        ...
    )
    r.raise_for_status()
    resp = r.json()
    errored = False

except Exception as e:
    resp = _parse_json(e)
    errored = True

except r.Timeout:
    errored = False

This is my first time handling/making post requests so please bear with me!

From what I've researched, in python the flow falls on the first except that matches the exception. In this case, place the timeout exception first.

import socket
import logging

errored = False
hostname = '10.255.255.1'
port = 443
socket.setdefaulttimeout(0.1)
try:
    sock = socket.create_connection((hostname, port))

except ZeroDivisionError:
    print('must not enter here')

except socket.timeout as err:
    print('timeout')
    errored = False
except Exception as ex:
    print('base exception')
    errored = True
except:
    print('unknown exception')
    errored = True
else:
    print('success')
finally:
    print('This is always executed')

This code example makes a request that will timeout, will always fall into

except socket.timeout as err:

and then in finally. you can change the order of except to test.

here a link about trycatch.

Hope this helps
