Solve the following python programming problem given the following code:
def _sort_hostnames(hostname_list) : 
    '
    sort minion ids favoring in order of:
        - FQDN
        - public ipaddress
        - localhost alias
        - private ipaddress
    ' 
    punish = ['localhost.localdomain', 'localhost.my.domain', 'localhost4.localdomain4', 'localhost', 'ip6-localhost', 'ip6-loopback', 'ipv6-localhost', 'ipv6-loopback', '127.0.2.1', '127.0.1.1', '127.0.0.1', '0.0.0.0', '::1', 'fe00::', 'fe02::'] 
    def _key_hostname(e) : 
        if (' ' in e) : 
            first = 1 
else : 
            first = (- 1) 
if (e in punish) : 
            second = punish.index (e) 
else : 
            second = (- 1) 
third = e.count (':') 
        e_is_ipv4 = ((e.count ('.') == 3) and (not any ((c.isalpha () for c in e)))) 
        if e_is_ipv4 : 
            if e.startswith ('127.') : 
                fourth = 1 
else : 
                fourth = 0 
else : 
            fourth = (- 1) 
fifth = (- e.count ('.')) 
        sixth = (- len (e)) 
        return (first, second, third, fourth, fifth, sixth) 
return sorted (hostname_list, key = punish) 

    
    

    Fix the buggy line: return sorted (hostname_list, key = punish)
