is there a pythonic way to try something up to a maximum number of times? [duplicate]

Answer 1

UPDATE: there is a better maintained fork of the retrying library called tenacity, which supports more features and is in general more flexible.

Yes, there is the retrying library, which has a decorator that implements several kinds of retrying logic that you can combine:

Some examples:

@retry(stop_max_attempt_number=7)
def stop_after_7_attempts():
    print "Stopping after 7 attempts"

@retry(wait_fixed=2000)
def wait_2_s():
    print "Wait 2 second between retries"

@retry(wait_exponential_multiplier=1000, wait_exponential_max=10000)
def wait_exponential_1000():
    print "Wait 2^x * 1000 milliseconds between each retry,"
    print "up to 10 seconds, then 10 seconds afterwards"
