Solve the following python programming problem given the following code:
def detach_device_with_retry(self, get_device_conf_func, device, persistent, live, max_retry_count = 7, inc_sleep_time = 2, max_sleep_time = 30) : 
    'Detaches a device from the guest. After the initial detach request,
        a function is returned which can be used to ensure the device is
        successfully removed from the guest domain (retrying the removal as
        necessary).

        :param get_device_conf_func: function which takes device as a parameter
                                     and returns the configuration for device
        :param device: device to detach
        :param persistent: bool to indicate whether the change is
                           persistent or not
        :param live: bool to indicate whether it affects the guest in running
                     state
        :param max_retry_count: number of times the returned function will
                                retry a detach before failing
        :param inc_sleep_time: incremental time to sleep in seconds between
                               detach retries
        :param max_sleep_time: max sleep time in seconds beyond which the sleep
                               time will not be incremented using param
                               inc_sleep_time. On reaching this threshold,
                               max_sleep_time will be used as the sleep time.
