How to retry after exception?
Do a while True inside your for loop, put your try code inside, and break from that while loop only when your code succeeds.
for i in range(0,100): while True: try: # do stuff except SomeSpecificException: continue break
I prefer to limit the number of retries, so that if there's a problem with that specific item you will eventually continue onto the next one, thus:
for i in range(100): for attempt in range(10): try: # do thing except: # perhaps reconnect, etc. else: break else: # we failed all the attempts - deal with the consequences.
The retrying package is a nice way to retry a block of code on failure.
For example:
@retry(wait_random_min=1000, wait_random_max=2000)def wait_random_1_to_2_s(): print("Randomly wait 1 to 2 seconds between retries")
