I am using Twython to post updates on Twitter. Lately there is now and
then a problem with my internet connection. I am using:
posted = twitter.update_status(status = message,
in_reply_to_status_id = message_id,
trim_user = True)
What would be the best way to catch a connection error and try it (for
example) again maximum three times with a delay of one minute?
At the moment I solved it with the following:
max_tries = 3
current_try = 1
while True:
try:
posted = twitter.update_status(status = message,
in_reply_to_status_id = message_id,
trim_user = True)
return posted['id']
except TwythonError as e:
print('Failed on try: {0}'.format(current_try))
if not 'Temporary failure in name resolution' in e.msg:
raise
if current_try == max_tries:
raise
current_try += 1
time.sleep(60)
Is this a good way to do it, or can it be improved on?
When it goes OK I just return from the function.
If it goes wrong for something else as failure in the name resolution
I re-raise the exception.
When the maximum tries are done I re-raise the exception.
Otherwise I wait a minute to try it again.
You have a 'while' loop with a counter; you can replace that with a
'for' loop.
