Can tenacity
handle this or should I implement retry wrapper myself if I need to catch exception do a callback and get back to next try?
send → fetch error → if recoverable → run callback → try send again
When I use a simple case with this code, next try never happened:
class A:
a = 0
@retry(stop=stop_after_attempt(7))
def never_give_up_never_surrender(cls):
try:
1/cls.a
print('possibly wrong')
except ZeroDivisionError:
cls.a+=1
print('next try')
else:
print('done')
There is a way:
def error_callback(retry_state):
# error handler
if isinstance(retry_state._exception(ZeroDivisionError)):
print("Can't handle it")
else:
print("Handled")
@retry(retry_error_callback=error_callback):
def zero_division():
a = 1
b = 0
a/b
