Fixing decorators arguments

Question

I have the following third party decorator:

def retry(exception_to_check, tries=4, delay=3, backoff=2, logger=None):

I would like to make another decorator, @my_retry, that is similar to @retry, but with fixed arguments.

I've tried doing it using functools.partial:

my_retry = partial(retry, RETRY_EXCEPTIONS, tries=5, delay=5, backoff=3, logger=logging)

But when I use the new decorator I get the following exception:

TypeError: retry() got multiple values for keyword argument 'tries'

What am I doing wrong?

Answer 1

What you need to do is to make a wrapper around retry, like this

def my_retry(retry_exceptions, tries=5, delay=5, backoff=3, logger=logging):
    return retry(retry_exceptions, tries, delay, backoff, logger)

and use @my_retry().
