Repeat Python function call on exception?

Question

Hey everybody I\'m working on a data scraping project and I\'m looking for a clean way to repeat a function call if an exception is raised.

Pseudo-code:

Answer 1

To raise Exception as usual after n retries

from functools import wraps

def retry(times):
    """
    Decorator to retry any functions 'times' times.
    """
    def retry_decorator(func):
        @wraps(func)
        def retried_function(*args, **kwargs):
            for i in range(times - 1):
                try:
                    func(*args, **kwargs)
                    return
                except Exception:  
                    pass
            func(*args, **kwargs)

        return retried_function

    return retry_decorator


# test

attempts = 3

@retry(4)
def function_that_raises_error():
    global attempts
    if 0 < attempts:
        print("fail")
        attempts -= 1
        raise Exception

    print("pass")

function_that_raises_error()
