Try...except not catching NoSuchElementException in python and selenium

I have this code
below:

def
            test_counter(self):
 try:
 if
            self.driver.find_element_by_id(self.counter).text ==
            'texttexttext':

 return True
 except
            NoSuchElementException and StaleElementReferenceException:

            self.fix_error()
 return
            False

And I cannot
figure out why the NoSuchElementException or the
StaleElementReferenceException are not being caught.
