Pythonic way of retry running a function [duplicate]

Answer 1

this definitely calls for a decorator.

you'd probably want something like:

import functools
def retry(func):
    @functools.wraps(func)
    def wrapper(*args, **kwargs):
        retExc = None
        for i in xrange(4):
            try:
                return func(*args, **kwargs)
            except Exception, e:
                retExc = e
        raise retExc
    return wrapper

and then to run your code, just use:

@retry
def some_request(...):
    ...

you could make it fancier by adding in a little sleep, adding a numTimes to retry, etc, but this will do it.
