Closing logger to rename directory

[malcoverc]

I have 2 functions, one is creating a logs in directory and other should rename directory to "directory_old" and then create new "directory". Problem is that I will not have acces to rename this directory untill logger is initiated so I want to disable loggers, rename directory and enable loggers again. I know there is module ".close()" but in my case it doesn't work at all or I don't know how to use it(more probably).

def start_logger(self):
    self.log = logging.getLogger()
    self.log.handlers = []
    Filehandler = logging.FileHandler(filename="directory\\logs\\stages" + '.log', mode="w")
    self.log.info("succes")
    self.log.addHandler(Filehandler)


def clear_logger(self):
    #close logger??
    self.log.close()
    os.rename("directory","directory_old")
    #create new directory
    os.mkdir("directory\\logs")
    #start logger again
    #???
