How to retry after exception in python?

I have a loop starting with

for i in range(0, 100)
. Normally it runs correctly, but sometimes it fails due to network conditions. Currently I have it set so that on failure, it will
continue
in the except clause (continue on to the next number for
i
).

Is it possible for me to reassign the same number to
i
and run through the failed iteration of the loop again?

Answer

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
